Abstract: A method for quantizing an image includes obtaining M batches of images; creating histograms by training based on each of the M batches of images; merging the histograms for each of the batches of images into a merged histogram; obtaining a minimum value from all minimum values of the M merged histograms and a maximum value from all maximum values of the M merged histograms; defining ranges of new bins of a new histogram according to the obtained minimum value, the obtained maximum value, and the number of the new bins; and estimating a distribution of each of the new bins by adding up frequencies falling into the ranges of the new bins to create the new histogram. The amount of the images in each of the M batches of images is N, and each of N and M is an integer and equal to or larger than two.
