1. A method for compressing a video stream, comprising:
retrieving a plurality of frames corresponding to the video stream;
for each of two or more sequential frames of the plurality of frames of the video stream:
extracting Key Point Descriptors (KPDs) for the respective frame;
processing the respective frame using Principle Component Analysis (PCA) followed by vector quantization, resulting in a quantized explained variance matrix for the respective frame;
storing the quantized explained variance matrix for the respective frame, the quantized explained variance matrix represents the respective frame with reduced dimensions; and
storing the KPDs for the respective frame.
