METHOD AND DEVICE FOR GENERATING THERMODYNAMIC DIAGRAM

摘要

Embodiments of this application relate to the field of image processing, and provide a method and an apparatus for generating a heatmap, so as to implement that a heatmap reflects a region feature continuously and accurately, and a change in an image zoom ratio does not affect continuity and accuracy of the heatmap. Specific solutions include: dividing a current display region of an original image on a screen into cells; calculating basic heat of a heat point region in each cell according to statistics and a heat weight for generating a heatmap this time; then calculating, according to the basic heat of the heat point region in the cell, diffusion heat to which each pixel in the current display region is subject; obtaining total heat of each pixel in the current display region; and presenting, in the current display region of the original image according to a preset heat presentation correspondence, a color corresponding to the total heat of each pixel in the current display region, to obtain a heatmap of the current display region. This application is used to generate a heatmap.
