Abstract
Image processing methods and image processing apparatuses are provided. The image processing method comprises: determining at least one region of interest in an image; determining a parameter of interest of pixels in the image at least according to distribution of the at least one region of interest in the image; determining target positions of the pixels according to the parameter of interest of the pixels and a reduction ratio; and obtaining, according to the target positions of the pixels, a reduced image corresponding to the image. A proportion occupied by pixels of each region in a reduced image after compression is determined according to a degree of interest of a user in each region in an image, to cause a region appreciated by the user to be presented with high quality during restoration, and facilitate image processing after compression.
