Finger Vein Recognition with Anatomy Structure Analysis

Finger vein recognition denotes a novel technique that is completely based on the analysis of physiological characteristics to work through biometrics. The pattern of veins from the palmer side of the finger is used as identification and is then analyzed for performing the authentication in a later period. This article on Finger vein recognition with anatomy Structure Analysis talks about all the aspects necessary for finger vein recognition research and system development.

Let us first start with the description of different methods used in finger vein pattern extraction 

FINGER VEIN PATTERN EXTRACTION METHODS

The methods of light reflection and light transmission are used for the extraction of patterns in the finger vein.

• Light Transmission
  • In the light transmission method, disorders of light and image sensors are placed on either side of the finger
  • Near-infrared light is used for capturing the finger vein patterns by passing it through the fingers
  • In turn the image sensor captures the near-infrared light that reaches it
• Light Reflection         
  • In the light reflection method, the Source of light and sensor for the opening image is located on the same side
  • Image sensor is used in capturing the light reflected from the finger surface

Is vein recognition biometrics reliable? Yes. At finger vein recognition with anatomy structure analysis, we not only provide technical explanations regarding the working of fingerprint scanners but also give you expert answers to the most important frequently asked questions in the field. In this regard we want you to consider the following points to understand the reliability of finger vein recognition

• Features of the veins in the fingers are preferred for the reason that they cannot be altered through any surgical operations.
• Hence vein recognition is considered to be one of the most trusted methods for authentication.

Since finger vein recognition has become the promising method of ensuring security in many systems, understanding all its processes play a very significant role. Accordingly, the process involved in extracting required objects from the finger vein images is important.

What is vein object extraction?

• Vein object extraction is the first step in finger vein recognition system
• Obtaining vein ridges is the significant function for which this process is carried out
• The performance of this recognition is a function of the finger vein anatomical structure
• The quality of the finger vein recognition system can be expanded by integrating the patterns associated with the veins and non-vein characteristics

It is crucial to note that the palmar side of the finger extends between fingertip and finger root as a result of which a network of two to three core veins and their associated branches over the two-finger boundaries is formed.

If you wish to dig deep into the science behind vein recognition then you can get in touch with us and gain access to collections of thousands of reliable books, standard references, and benchmark sources related to finger vein recognition. We also provide you with the most needed explanations for your project.

Let us now discuss the anatomical structures and their features for the purpose of finger vein recognition 

Anatomy structure features for Finger Vein Recognition

On talking about the anatomy-based features that make finger vein recognition system highly relevant is the following,

• Vein continuity
  • The pattern of veins which starts from the of the finger continuously featured until its foot
  • That is the vein pattern is regular and continuous which is not broken in the middle
  • Also interconnection is established in every branch as well as among various branches
• Solidity and smoothness
  • Every vein pattern branch is a solid curve and is also smooth
  • Sudden and Cutting alterations in the vein width are not encountered
  • Vein pattern is also observed in a well-structured manner without holes and burr
• Directional pattern
  • The vein branch pattern is observed as parallels to the fingers
  • Any other branches apart from the main one are seen at arbitrary angles
  • Orientation of vein growth is seen as a dynamic parameter in all vein branches
• Variation in width
  • Vein patterns’ outer diameter is dynamic where coarse variations are observed as we move from finger root to tip as well as along core to sub-branch
  • The proximal outer vein branch diameter and finger middle segment difference is determined
  • When the Vein position is at the proximal finger segment, the diameter is determined as a range between 0.68 and 0.88 millimeter
  • Whereas at the middle finger segment, the diameter is observed to be ranging from 0.52 to 0.76 millimeter

These are the major characteristic features of the fingerprints structures. The advancements of technology allow us to acquire and access digital data all around the world while it has become a difficult undertaking to maintain good security and data secrecy. On par with all the latest trends and developments, we focus on updating ourselves regularly so as to go with present and future demand in finger vein recognition research.

We created a number of finger vein pattern-based witnessing technologies that are being used on a real-time basis. Check out our website for the list of our successful finger vein recognition with anatomy Structure Analysis projects. Let us now talk more about the imaging characteristics of finger vein

Finger Vein Imaging Characteristics

• Near-infrared light energy is absorbed heavily by hemoglobin inside the veins while acquiring images but it can readily pass through other tissues inside the fingers, resulting in a vein pattern with lower gray levels when compared with the non-vein regions in the acquired image patterns.
• As a result, every vein pattern’s cross-sectional outline seems to have a valley form.
• Yet, it is discovered that perhaps the valley-shaped (half) and cross-sectional characteristic of the vein pattern actually occurs in moderate photos after a thorough examination of the finger vein images.

The algorithms and functions involved in digital data security by unique Identity verification are available for reference on our website. Our engineers have used appropriate platforms and software for filtration, augmenting, fragmenting, extraction of features, deep learning, and categorizing the finger vein image. 

We are well aware of the processes, components, and algorithms needed for finger vein recognition techniques to be done in all these stages. We have also found potential solutions to the research issues in finger vein anatomy. What are the issues in finger vein anatomy structure? 

Finger Vein Anatomy Structure Issues and Solutions 

• Noise
  • The association of valley shaped cross-sectional profile with non vein point is the reason for the noise
  • The characteristics of smooth nurse and continuity are found unmatched in this anatomical structure
  • Solution – Denoising is the method used for processing noise 
• Breakpoint
  • The blurring of vein pattern leads to the formation of breakpoints
  • Continuity mismatches cause breakpoints to occur
  • Solution – Connecting methods are involved in processing breakpoints
• Hole
  • The inaccurate orientation of the veins lead to the formation of holes
  • The anatomical feature of solidness is the unmatched component leading to holes
  • Solution – Filling methods are used for processing holes

Since our technical team has experience of more than 15 years of finger vein image-based projects, we have devised ideal alternatives to all such problems. Also with the improvements in the field of health informatics and life and medical sciences, the demands on finger vein recognition technology are also increasing. We have been able to provide high-quality project support including both technical and literary aspects like writing thesis and proposals in finger vein recognition mainly because of the arduous efforts of our experts. We gained expertise in finger vein pattern Denoising about which we have discussed below

Denoising in Finger Vein Patterns 

• Inside a thinned pattern of veins, there seem to be two types of noise
• Isolated noise within the non-vein portion
• Roughness just on vein pattern.
• The regions among all linked areas inside this binary finger vein images are assessed for solitary noise, and any interconnected domains including an area much less than the actual size level are considered as isolated turbulence or noise and are eliminated.

For further details on Denoising processes, you can contact us. In relation to security and efficiency, the finger vein has more potential than conventional biometric technology. So you need to have a complete idea of all its processes, especially denoising.

Nonetheless, depending on the processor’s capability or the environment in which it operates, precision (accuracy) may well be compromised. We proposed many advanced approaches for improving finger vein recognition systems. Also quite importantly, the methods used in pattern recognition also play a primary role in its efficiency. So we will look into the non-vein and vein based recognition methods below

Finger vein vs. Non-vein recognition methods

• Methods for vein pattern recognition
  • Region growth and Gabor filters
  • Mean curvature and maximum curvature point
  • Repeated line tracking, wide line detector, and proposed method
• Methods for non – vein pattern recognition
  • LLBP and (2D) PCA
  • Super – pixel-based feature and Minutiae
  • DBC and LBP

Both of these methods involve several techniques and approaches for acquiring finger vein images, Pre-processing them, and analyzing. When compared to other hand-based biometric technologies, a finger vein-based biometric system has various advantages.

What are the advantages of finger vein recognition? As the finger vein pattern is indeed an anatomical trait, it is difficult to duplicate, and also finger vein recognition doesn’t really necessitate finger-sensor touch, which is advantageous from a cleanliness standpoint.

  • The following are the different aspects of principal component analysis
  • Two-dimensional principal component analysis (or 2DPCA)
  • Linear discriminant analysis (or LDA)
  • Two directional and two-dimensional principal component analysis
  • Transformation Matrix training requires additional practical application-based data
• Superpixel based feature
  • In this approach even though the rate of recognition is very high the process itself is highly time-consuming
  • The value or parameter based uncertainty makes the Recognition rate reproduction hard
• Scale-invariant feature transform
  • Finger vein images consist of the limited amount of minutiae
  • Performance of recognition is therefore not up to the mark
  • The formation of veins and finger displacement lead to difficulty in performing minutia and key point pairing
• High-level features
  • The following are certain examples of high-level features which are used in finger vein recognition
  • Vein textons map
