Problems solved by technology

[0003] In the process of image processing, we often use the mask layer to transparently mix the original image and the full effect image, but due to the rigidity of the mask layer, the processing effect is not good, and the solution we often use is to directly Use Gaussian blur on the mask layer to make the transition natural
However, Gaussian blur will cause the entire mask layer to expand, especially in beauty treatment, which will cause the loss of details such as eyes, eyebrows, lips, etc., resulting in poor beauty effects

Embodiment Construction

[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0025] like figure 1 Shown, the optimization method of a kind of image edge of the present invention, it comprises the following steps:

[0026] 10. Receive the original image;

[0027] 20. Load the mask image in the area to be processed of the original image;

[0028] 30. Calculate the minimum value on the mask image to obtain the minimum value image;

[0029] 40. Perform blurring processing on the minimum value map to obtain a blurred image;

[0030] 50. Mixing the original image and the blurred image to obtain the result image.

[0031] Th...

Abstract

The invention discloses an optimizing method of an image border. The method comprises the following steps: loading a masking image at an area in which an original image is to be processed; calculating the minimum value of the masking image to obtain a minimum image; performing fuzzy processing for the minimum image to obtain a fuzzy image; mixing and calculating the original image and the fuzzy image to obtain a final image. With the adoption of the method, the transition border between the area after being processed and the area before being processed of the result image is natural; particularly the eyes, eyebrows, lips and other details can be maintained well during beautifying the image, and as a result, the beautifying effect is improved.

Description

technical field [0001] The invention relates to an image processing method, in particular to an image edge optimization method. Background technique [0002] Mask is a special selection area, its purpose is not to operate the selection area, on the contrary, it is to protect the selection area from being operated, and at the same time, the places not in the mask range can be edited and processed. The layer mask in PS can only use black, white and gray. Black is to cover the content of the current layer and display the content of the layer below the current layer. White is to display the content of the current layer, and gray is half. Transparent, the content of the layer below the previous layer is faintly visible. [0003] In the process of image processing, we often use the mask layer to transparently mix the original image and the full effect image, but due to the rigidity of the mask layer, the processing effect is not good, and the solution we often use is to directly ...
