experiment example 1

[0078] Figure 3a shows a raw photographic image of a musical instrument, Figure 3b It shows the output image of the musical instrument after being processed by the image quality optimization method provided by the embodiment of the present invention. From Figure 3a and Figure 3b It can be seen from the figure that the method of the present invention can effectively improve the definition (resolution) of the image, and the distortion rate of the optimized image is very small.

experiment example 2

[0080] Figure 4a It shows an original photo of a character and scenery, and gives the relevant image parameters of the original photo, Figure 4b It shows the figure and scenery photo output after being processed by the image quality optimization method provided by the embodiment of the present invention, and provides the relevant image parameters of the optimized photo. From Figure 4a and Figure 4b It can be seen from the figure that the method of the present invention can effectively improve the clarity (resolution) of the photo, and the distortion rate of the optimized photo is very small.

experiment example 3

[0082] Figure 5 The image on the left is a normal video (1080p), Figure 5 The image on the right is a high-definition video (1080p) obtained after being processed by the method of the present invention.

[0083] Figure 6 On the left is the general video image before optimization and upgrade, Figure 6 The right side is the high-definition video image obtained after being processed by the method of the present invention.

[0084] Depend on Figure 5 From the comparison results, it can be concluded that the method of the present invention can upgrade and optimize low-resolution image content to high-resolution and good-definition image content (the resolution of the original image content can be increased by about 30%), which can improve The visual effect of the image improves the user's viewing experience.

[0085] Depend on Figure 6 According to the comparison results, it can be concluded that the further optimization and upgrading of the image quality of high-defini...

Abstract

The invention is applicable to the field of computer technology, and provides an image quality optimization method, a computer device and a readable storage medium. The method includes acquiring an original image to be processed; performing a first color space conversion on the original image to obtain a first image and a second image; based on the image quality enhancement algorithm, the first image being self-adaptively enhanced and enlarged, and the resolution being increased to obtain a preliminary enhanced image; combining the second image with the preliminary enhanced image to obtain a combined image; performing second color space conversion on the combined image to obtain a final enhanced image; outputting the final enhanced image. The invention can obviously improve the resolution(clarity) of the image without losing the authenticity of the image or the loss rate is very low, and is particularly suitable for the optimization and upgrading of the resolution image / photograph, comprehensively improving the quality of the image and improving the visual effect of the image.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to an image quality optimization method, a computer device and a readable storage medium. Background technique [0002] In more than 40 years, image processing has rapidly developed into an independent subject with strong vitality. Image enhancement technology has gradually involved in all aspects of human life and social production. [0003] However, the existing image enhancement technology generally uses an interpolation method to increase the size of the image before the original image is enhanced. However, after the image size is enlarged, the image will produce jagged edges and the resolution will decrease, resulting in a decrease in image quality. [0004] It can be seen that the existing image enhancement technology has the problems of reduced resolution and reduced image quality after the image is enlarged. Contents of the invention [0005] An embodiment o...
