Visual Media Processing Using MATLAB Beginner's Guide
By :
In this chapter, we presented the video acquisition functionality of MATLAB. The first part was dedicated to a thorough analysis of the Image Acquisition Tool, which is a basic GUI-based framework for video acquisition. After presenting a couple of examples on the usage of imaqtool, we moved on to a discussion on video compression and its great importance. The difference in compression ratios between still scenes and scenes with high motion was explained, using two practical, hands-on examples. Then, a small discussion on ways to work with uncompressed videos was carried out, followed by an example of processing video frames in chunks to save space. The next part of this chapter was focused on ways to create time-lapse videos using the command line, either without, or with processing of the acquired frames. The final part of the chapter revolved around the real-time video processing capabilities of MATLAB. In these sections, we discussed ways to speed up the acquisition and processing...
