Embodiment Construction

[0125] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, this application can

[0127] Please refer to FIG. 1, which is a flowchart of an embodiment of an image processing method of the present application. The method includes as

[0128] In step 101, edge-preserving filtering is performed on the first image based on the original image to obtain a filtered image.

[0130] The first image based on the original image can be the original image, in this case this step can be sampled

[0133] The down-sampling, also known as the process of reducing the image resolution. For example, for an N×M original

[0135] Through downsampling, the original image size and the radius of the filtering window can be reduced simultaneously, so the preservation can be improved.

[0139] Since the filtered image obtained in step 101 is edge-preserving and denoising, the texture in the original image i...

Abstract

The application discloses an image processing method, an image processing device, and an electronic device. Wherein, the image processing method includes: performing edge-preserving filtering on the first image based on the original image to obtain a filtered image; fusing the second image based on the original image and the third image based on the filtered image to obtain a fused image. With the above method, since the fusion operation with the second image based on the original image is performed after edge-preserving filtering, the texture details of the original image can be preserved to a certain extent while eliminating noise and preserving edges, thereby avoiding Due to the image distortion caused by the flat area being too smooth, the fused image is more realistic and the image quality is effectively improved.

Description

Image processing method, device and electronic device technical field [0001] The application relates to the field of image processing, in particular to a method for image processing. The present application also relates to a Like a processing device, and an electronic device. Background technique [0002] The image captured by the camera usually contains some noise (also called noise point) that affects the beauty of the image, These noises may be caused by random signals (also called noise) interfered with when capturing or transmitting images, or they may be What the object itself has, such as dark spots and blemishes in the face image. To enhance the beauty of the image, you can usually use Filtering techniques process images to remove noise. The most commonly used filter at present is the edge-preserving filter (also called the edge-preserving filter algorithm), among which the most classic one is the edge-preserving filter. is a bilateral filter. The filter...
