Implementing image modification functions using variable scanning orders

A method for implementing image modification functions via use of variable scanning orders, comprising:

• partitioning an image into a plurality of image blocks;
• identifying one or more image blocks of the plurality of image blocks associated with a region of interest (ROI), including identifying a remaining portion of an image block and processing the remaining portion of the image block with image blocks in a next row,
• scanning the one or more image blocks in an image modification order, comprising scanning the one or more of the image blocks in a row from right to left and scanning each row of a plurality of row from top to bottom;
• and
• arranging the one or more image blocks according to the image modification order to form a modified image including the region of interest (ROI), comprising arranging image blocks from each scanned row as rows on top of each other.

A non-transitory computer-readable storage medium having an executable stored thereon, which when executed instructs a processor to:

• partition an image into a plurality of image blocks;
• identify one or more image blocks of the plurality of image blocks associated with a region of interest (ROI), including identifying a remaining portion of an image block and processing the remaining portion of the image block with image blocks in a next row;
• scan the one or more image blocks in an image modification order, wherein scanning image blocks includes scanning the one or more of the image blocks in a row from left to right and scanning each row of a plurality of rows from bottom to top;
• arrange the one or more image blocks according to the image modification order to form a modified image including the region of interest (ROI), wherein arranging the one or more image blocks includes arranging image blocks from each scanned row as rows on top of each other;
• and crop the region of interest (ROI) in the modified image to form a new image.
