[0076] Example one:
[0077] Hereinafter, in conjunction with the accompanying drawings, the above method of extracting the main body of the product from the product image will be described in detail. image 3 It is the flow chart of the method for extracting the main body of the product from the product picture provided by this application. As can be seen from the figure, the method includes:
[0078] Step 301: Obtain the saliency of multiple selected regions in the picture corresponding to the picture data;
[0079] In this step, the saliency of multiple selected regions in a picture can be acquired through the existing saliency acquisition method, or through the following Figure 3A Describe the saliency acquisition process to acquire. Figure 3A The saliency acquisition methods shown include:
[0080] Step 3011: Obtain a first probability distribution histogram in the color space of each color in the selected area in the picture corresponding to the picture data;
[0081] Step 3012:...
Example Embodiment
[0121] Example two:
[0122] The following describes in further detail the method of obtaining image quality provided by the embodiments of the present application in conjunction with the accompanying drawings, please refer to Figure 4 , Which provides a flowchart of a method for obtaining image quality for this application. by Figure 4 It can be seen that the method of obtaining the image quality of this kind includes:
[0123] Step 401: Obtain the main body area of a potential product according to the saliency distribution of different selected areas in the picture in the picture;
[0124] In this step, first, in step 4011, the saliency of a plurality of selected regions is obtained; then, in step 4012, the saliency of the plurality of selected regions is normalized to obtain the picture For the saliency distribution of multiple selected regions in the picture, the process can refer to Figure 4A .
[0125] More specifically, in step 4011, all areas in the picture can be scanne...
