Abstract:
1. A method for reducing a size of an original image using a processor to perform the steps of the method comprising: segmenting the original image into a first image and a second image; determining a first transformation method based on characteristics of the first image; generating a first scaled image, having a smaller image size than the image size of the first image, from the first image, the first scaled image comprised of a plurality of first target pixels having respective values obtained using the first transformation method; determining a second transformation method based on characteristics of the second image; generating a second scaled image from the second image, the second scaled image comprised of a plurality of second target pixels having respective values obtained using the second transformation method; and combining the first scaled image and the second scaled image into a reduced size image having a smaller image size than the image size of the original image, wherein the first transformation method comprises: specifying a position of each first target pixel in the first scaled image; extracting, for each first target pixel, a plurality of pixels from the first image, which are located at a position corresponding to the position of the respective first target pixel in the first scaled image; and calculating the value of the respective first target pixel in the first scaled image based on values of the plurality of pixels extracted from the first image.
