Video Processing using Matlab Simulink

Analysis of multimedia processing i.e. video processing is referred to as handling videos for processing and producing the outputs through a sequence of frames. Mainly, it is intended to continuously stream a series of images for processing. In specific, it is used to process images to find a correlation, hidden information recognition, quality improvement, etc. Moreover, it also secures the information by signal encryption and decryption process in video processing using matlab projects.

For instance: surveillance cameras. In this, it collects images from different angled cameras and collages them into a single monitor in cyclic order for processing. Once again, video is a colossal collection of images in sequential order. For processing, this video is unpacked to obtain images as scenes. 

Fundamentals of Video Processing 

Techniques used for image processing are very efficient to investigate the video. These techniques analyze the video in the frame-by-frame method. In this, frames are nothing but the images sequence in video. Further, it enhances the video quality through the insertion of temporal data, the relation among frames, etc. And also, it is efficient to address issues of temporal signal entities such as, 

Limitations of Video Processing 

• Camera Motion
• Object Tracing
• Temporal Noise
• Object Behaviour
• Interaction, Object Motion

Below, we have listed out few important elements of video processing. 

Video Processing Elements

• Bit Rate
  • Amount of information traversed in the specific time period is called as bit rate
• Frame
  • Generally, video is a sequence of images where a single image is represented as a frame
  • In fact, the size of the frame is computed by multiplying the width and height of pixels
• Color
  • One of the pixel properties is color which is signified as a fixed number of bits
  • When there is a greater number of bits, generate color variation known as color depth

Now, we can see about developing steps for video processing. With an intention to make you more clear in video processing concepts, we have given this workflow. These steps will differ from other projects based on individual project needs. Likewise, we also give you an implementation plan with basic software and hardware requirements. In this, we also mention performance assessment parameters to examine the efficiency of your proposed system. Also, these metrics play a major role in enhancing project performance.  

On this page, we have given you a complete summary for exploring and developing a project of video processing using Matlab for PhD/MS scholars and final year students!!!

Overall Flow of Video Processing Using Matlab

• Step 1 – Acquire a digital image as input
• Step 2 – Perform the following operations
  • Abandoned object identification
  • Mobile object tracking
  • Human events classification
• Step 3 – Execute video-shot recognition and indexing from the above operations
• Step 4 – Store results to a database
• Step 5 – Collect user-query through user-interface
• Step 6 – Distribute user requested video from database to respective user

For illustration purposes, here we have selected one of the key processes of video processing as “feature extraction and tracking”. An individual portion of the video is known as a feature which can be anything like a car, signal light, person, etc. Usually, the frame is used as input and extract the essential features to collect in-depth information. This process of extraction is called feature extraction. Similarly, tracing a feature from one frame to another is called feature tracking. For instance: appearance, shape, motion, etc. Further, here we have given other differences in feature extraction and tracking.

Major 2 Processes in Video Processing 

• Feature Extraction
  • Extract informative features from frame (static image)
  • Features of one frame are independent of other frames of video
  • Object segmentation technique uses a single frame to extract specific feature
• Feature Tracking
  • Trace required features between several frames
  • Features of one frame are dependent on other frames of video
  • Object tracking technique uses multiple frames to extract stable features

Next, we can see about important research challenges of video processing. In general research work, scholars handpick any of the recent research issues in their desired research area. Then, choose a suitable research solution to solve the selected issue inefficiently way. In the end, prove the proposed research solution as best than existing approaches. This procedure is common for all kinds of the research field.

Our resource team is unique in recognizing research problems and gaps in current areas. To attain the best research ideas, we refer to all possible research sources and materials like articles and magazines. From our current study, we have presented you with four main issues of video processing. 

Important four issues of Video Processing 

• Enhancement
  • When an image is blurred, low contrast and noisy, the image may lack quality
  • So, it is essential to enhance the quality of the image by enhancement technique
  • Although there are techniques, it still looking for effective techniques
• Compression
  • At a moment, more applications are using large-scale data which cause trouble while transmission
  • In that case, compression reduces data size and helps to transmit data in high-speed
  • Here, compression efficiency can be improved by motion-compensated prediction
  • If the prediction is not accurate, then it may affect compression performance. For instance: low bit rate in video conferencing
  • So, it is required to improve and use efficient techniques
• Security
  • For any kind of application, security is a foremost factor that needs to consider at first
  • Nowadays, both individual and business people are demanding this factor in their applications
  • In the case of multimedia data, several cryptographic techniques are used like AES, RSA, etc.
  • But, still, the threats of security attacks are increasing more in web-based data
  • So, it is required to develop robust security control mechanisms
• Pattern Recognition
  • Object recognition is a primary task in video processing
  • However, it does not have effective solutions in high accuracy
  • So, it is considered as challenging task until now

To the continuation of research issues, now we can see about significant research solutions. By the by, research solutions are nothing but the latest techniques, methods, and algorithms that are suitable for cracking research challenges/issues. Usually, we suggest advanced solutions to handle complex problems. Further, we also make hybrid techniques and new algorithms for special scenarios. Overall, our proposed solutions are sure to achieve the targeted research objective. Also, we suggested solutions that are lightweight to do the simple computation for resource preservation.
