Abstract
A method for transparentizing a target object of a video includes following steps performed by a processor: extracting a target block corresponding to an target object from a frame of the video; setting a target transparentizing weight corresponding to the target block; performing a dilation operation upon the target block to generate a dilation outline enclosing the target block; setting a dilation transparentizing weight according to a dilation region, wherein the dilation region is a region inside the dilation outline and outside the target block; cutting a background block from the frame according to the dilation outline; and performing an overlapping operation according to a previous background block, the background block, the target block, the target transparentizing weight, the dilation region, and the dilation transparentizing weight to generate an output frame, wherein the previous background block does not correspond to the target object.
