Abstract:
1. A non-transitory computer readable medium (CRM) containing programming instructions that cause a processor to perform a method for: image encoding using a Binary Partition Tree (BPT), comprising: performing the BPT on a reference frame; detecting blocks, each having a difference in a pixel value exceeding a threshold value in a current frame, based on a result of the BPT of the reference frame; performing the BPT of the current frame on the detected blocks; and generating a block list of the reference frame based on a result of the BPT on the reference frame, after performing the BPT on the reference frame; wherein detecting blocks, each having a difference in a pixel value exceeding a threshold value in a current frame, based on a result of the BPT of the reference frame comprises: calculating a residual pixel value of the current frame by subtracting a pixel value of the current frame from a pixel value of the reference frame; calculating a pixel processing value by subtracting a threshold value from the residual pixel value of the current frame; and comparing the pixel processing value with a specific value and detecting the blocks each having the pixel processing value equal to or lower than the specific value, based on a result of the comparison.
