Method for automatically comparing content of images for classification into events |
摘要 |
A method for comparing image content of first and second images, the method comprises the steps of extracting a portion of both the first and second images both of which portions are determined to include a main subject area of each image; dividing the main subject area of the images into a plurality of blocks; computing a color histogram for one block in each image; computing a histogram intersection value between the block of the first image and the block of the second image; and determining a first threshold value for the computed histogram intersection value that determines similarity between the block in the first image and the block in the second image.
