ABSTRACT:
A system and method for efficient image compression begins by segmenting an input image into a current and previous window using a loading module. An encoding module compares the current and the previous window. If the current window does not match the previous window, the encoding module alters the dimensions of the current and previous windows and repeats the comparison. If a match is found, the encoding module instructs the loading module to continue to segment the image using the altered window dimensions. In this manner, the system's segmenting is in step with the natural cycle of repetition in the input image.
