Abstract
A video encoder may compare frames to generate a difference frames. The difference frame may be apportioned to generate a plurality of portions. Portions meeting a threshold pixel number condition are selected for compression. The threshold pixel number condition may measure the number of pixels which exceed an intensity threshold.
Claims15
An encoder, comprising:
- an input to receive video comprising video frames;
- a difference module to compare a previous frame with a current frame to generate a difference frame;
- a segmentation module to segment the difference frame into a plurality of segments, each segment comprising a plurality of pixels;
- a segment selector to select segments of the plurality of segments having a number of pixels exceeding an intensity threshold that meets a threshold condition;
- a compressor to compress each selected segment using an intra-coding compression method.

A method, comprising
- obtaining a pair of video frames;
- obtaining a delta frame by comparing the pair of video frames;
- apportioning the delta frame into a set of portions, each portion comprising a set of pixels;
- for each portion of the set of portions:
- counting a number of the pixels of the set of pixels of the portion that meet a threshold change condition;
- and
- if the number of pixels that meet the threshold change condition is at least a threshold number, compressing the portion.

A non-transitory computer readable medium, storing instructions executable by a processor to:
- obtain a difference frame comprising a difference between a first video frame and a second video frame;
- divide the difference frame into blocks, each block comprising a set of pixels;
- and
- compress any of the blocks having a threshold number of pixels that meet an intensity threshold determined from a noise level of a source of the first and second video frames.
