Patent ID: 8031782

Claim:
A method for producing a video image of an object, comprising the steps: a. providing a digitized image frame of said object and storing said digitized image frame in a memory device of a computer processor; b. providing a decimated WT of said digitized image frame; c. discarding high-frequency components of said decimated WT thereby producing a pre-processed frame; said step of pre-processing including a single level frame size reduction according to the following steps: (1) for every row in input frame pFrameIn: i. compute the decimated low-frequency Haar WT for consecutive pixels; ii. store in half the width of pFrameIn the resulting values; iii. at end of row, store the last pixel unchanged; (2) for every 2 consecutive rows in modified pFrameIn: i. compute the decimated low frequency Haar WT of corresponding pixels in the 2 rows column by column; ii. store the resulting values in output frame pFrameOut; iii. advance row position by 2; and (3) store the last row of the modified pFrameIn in pFrameOut last row: d. compressing said pre-processed frame using a video codec thereby producing a compressed video frame; e. decompressing said compressed video frame using said codec; and f. recreating a full sized image of said frame using post-processing using low-frequency parts of the WT and the last pixel of every row and column of the original image before the WT.
