The embodiment of the invention provides a filtering parameter adjusting method and device, and relates to the technical field of image processing. The method comprises the steps: obtaining frame difference information between a first image and a reference image, the reference image being an image determined based on an image collected before the first image; a target detection result of the first image is obtained, and the result comprises an area where a detected target is located and the type of the detected target; determining each foreground area in the first image according to the frame difference information and the result; and according to each foreground region, filtering parameters for filtering the first image are adjusted, and the filtering parameters comprise at least one of filtering region information, time-space domain filtering weight, filtering mode and filter coefficient. By applying the scheme provided by the embodiment of the invention to adjust the filtering parameters, the filtering effect can be improved.
Description
technical field [0001] The present application relates to the technical field of image processing, and in particular to a filtering parameter adjustment method and device. Background technique [0002] When performing image processing, in some cases, it is necessary to perform target detection on the image to obtain the area where the target is located in the image, and perform special effect processing on the area where the detected target is located. For example, when the above-mentioned target is a human face, it is necessary to detect the area where the human face is located in the image, and perform processing such as beautification on the above-mentioned area where the human face is located. [0003] However, the image quality collected under extreme conditions such as low illumination is poor. In this case, affected by the image quality, when performing target detection on the image, not only the detection accuracy is low, but also special effects are applied to the a...
