Embodiment Construction

[0035] Please refer to figure 1 A preferred embodiment of the image processing device 100 of the present invention includes a foreground object confirmation module 11 , a sampling module 12 , a fitting module 13 and a background removal module 14 .

[0036] The foreground object confirmation module 11 is used to confirm the foreground object in the picture to be processed.

[0037] In one embodiment, the foreground object confirmation module 11 pre-stores several images, and the foreground object confirmation module 11 combines an image formed by a pixel value densely distributed area in the picture to be processed with the pre-stored several images For comparison, if the similarity exceeds the first preset threshold, the foreground object confirmation module 11 will confirm the image formed by the area where the pixel values ​​are closely distributed as a foreground object.

[0038] In another embodiment, the foreground object confirmation module 11 analyzes the pixels in th...

Abstract

An image processing device comprises a foreground object confirmation module, a sampling module, a fitting module and a background removal module. The foreground object confirmation module is configured to confirm a foreground object in an image to be processed, and after the foreground object confirmation module confirms all the foreground objects in the image to be processed, the foreground object confirmation module confirms other areas in the image to be processed as a background area; the sampling module is configured to divide the background area into a plurality of subareas, and the sampling module performs sampling of pixel values in the subareas to calculate the sampling feature pixel values of the subareas; the fitting module is configured to calculate the pixel value function of each pixel point of the subareas through the sampling feature pixel values; and the background removal module is configured to subtract the pixel values of the pixel points in the background area obtained through calculation of the fitting module from the image to be processed to obtain the images of the foreground objects. The present invention further provides an image processing method.

Description

technical field [0001] The present invention relates to an image processing device, and also relates to an image processing method. Background technique [0002] In the field of image processing, image segmentation usually needs to extract foreground objects from the original image. The method of extracting the foreground is to distinguish the foreground and background of the image by defining multiple pixel value thresholds. This method defines multiple pixel value thresholds, which requires multiple calculations and requires more calculation time. Contents of the invention [0003] In view of this, it is necessary to provide a faster and more accurate image processing device and image processing method. [0004] An image processing device, comprising: [0005] A foreground object confirmation module, the foreground object confirmation module is used to confirm the foreground object in the picture to be processed, after the foreground object confirmation module confirms...
