Posture recognition method, apparatus and device, and computer program product

The invention relates to the field of image processing, and provides a posture recognition method, device and equipment and a computer program product. The posture recognition method comprises the following steps: segmenting a target video image into video sub-images, and determining the sum of pixel differences of the video sub-images in adjacent video images based on pixel gray values in the video sub-images; segmenting a region image determined based on the sum of the pixel differences of the video sub-images to obtain a suspicious object image; and segmenting an object effective area in the suspicious object image, and determining an object posture based on the object effective area. According to the method, the video image is segmented through multi-dimensional multiple iterations, and the fine-granularity image of the whole image is compared and distinguished by adopting the improved histogram algorithm, so that the position of the suspicious human body under the family background can be quickly and eff
