Reading PCM Files: PCM Files as Storage Format for Real Optical Flow Fields

This MATLAB code is designed to read PCM files, a file format used for storing real optical flow field data. In experimental research, optical flow fields represent a crucial data type as they help analyze object motion patterns within image sequences. The code I developed parses PCM files and converts them into visualizable optical flow field representations. Key implementation aspects include file I/O operations using fopen/fread functions, binary data parsing according to PCM specifications, and visualization through quiver plots or color coding techniques. When using this code, attention must be paid to file path configuration and format compatibility details. Furthermore, the code can be integrated with other algorithms and analysis tools (such as optical flow filtering, motion segmentation, or velocity calculation modules) to enable deeper investigation of optical flow data. The implementation handles data dimensionality and coordinate system transformations to ensure accurate vector field reconstruction. Overall, this MATLAB code serves as a practical tool that assists researchers in better understanding and analyzing optical flow field data through programmable data extraction and visualization capabilities.
