A MATLAB-based implementation of fractal image compression enhanced with the Discrete Cosine Transform (DCT), focusing on optimizing compression ratio, PSNR, and memory usage.

This implementation assumes that a Point2D structure has been defined to represent 2D points with x and y coordinates, and that a vector of Point2D objects has been provided to represent the input data points. The implementation uses a recursive algorithm to subdivide the 2D space into quadrants and store the input data points in the appropriate ..
