Abstract

The invention relates to an image segmentation method and device and a storage medium, and belongs to the field of image processing. The method comprises the following steps: inputting a target imageto be processed into a head detection model, and determining a first target region in the target image based on the head detection model; determining a second target area according to the first targetarea; inputting a second target area into a pixel classification model, and determining a classification mark of each pixel in the second target area based on the pixel classification model; determining a foreground region of the second target region based on the classification identification of each pixel in the second target region; based on the head detection model and the pixel classificationmodel, extracting the second target region containing the target object, and determining the foreground region of the second target region. The method reduces the interference of the background region except the second target region in the target image, reduces the computation amount, and saves the time. And the head of the target object is detected first and then the whole target object is detected, which improves the accuracy.

Description

technical field [0001] The present disclosure relates to the field of image processing, and in particular to an image segmentation method, device and storage medium. Background technique [0002] An image usually includes a foreground area and a background area, and image segmentation technology can determine the foreground area and the background area in the image, and distinguish the foreground area from the background area so that the foreground area or the background area can be processed separately. Widely used in target detection, object tracking, video surveillance, face recognition and other fields. [0003] The display color of any pixel in the image has the following correlation with the non-transparency of the foreground color, background color and foreground color of this pixel: I=αF+(1-α)B, wherein, I represents the display color of the pixel, F represents the pixel The foreground color of the pixel, B represents the background color of the pixel, and α represe...
