According to examples, a system for implementing image modification functions via use of variable scanning orders is described. The system may include a processor and a memory storing instructions. The processor, when executing the instructions, may cause the system 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), and scan the one or more image blocks in an image modification order. The processor, when executing the instructions, may then arrange the one or more image blocks according to the image modification order to form a modified image including the region of interest (ROI) and crop the region of interest (ROI) in the modified image to form a new image.

Implementing image modification functions using variable scanning orders

For encoding, a frame of video data can be segregated into macroblocks, which can be segregated into slices, which in turn can be segregated into slice groups. A macroblock identifier (ID) can be associated with each of the macroblocks. When at least one slice from each of the slice groups has been encoded, the macroblock IDs associated with the encoded slices can be compared to determine an order in which the encoded slices are to be placed in an access unit for the frame. Of the encoded slices, the slice that includes the macroblock with the lowest macroblock ID will be placed in the access unit before the other encoded slices.
