Method and device for determining perception amount of image and method and device for encoding image

Abstract

The invention discloses a method and a device for determining a perception amount of an image and a method and a device for encoding the image, which are used for solving the problems of the prior art that the color perception amount and the space perception amount of the image cannot be accurately determined and the quality of transmitting the image is reduced. The method for determining the perception amount of the image comprises the following steps of determining each color difference component of a pixel point aiming at each pixel point in the image and determining a color flatness amount of the image on each color difference component and a color variable quantity; and further determining the color perception amount of the image on each color difference component and determining the color perception amount of the image. The color difference component of each pixel point is determined according to a color pixel value of each pixel point of the image in the embodiment and the color flatness amount and the color variable quantity of the image are further determined; and the color perception amount of the image is determined according to the color flatness amount and the color variable quantity, so that the color perception amount of the image can be accurately determined.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method and device for determining the perceptual quantity of an image and encoding the image. Background technique [0002] Images are the main way for people to obtain information in daily life. In practical applications, various devices are usually used for image transmission and display. When the sending end wants to send some image data to be sent to the receiving end, it needs to encode the image data to be sent, and send the encoded image data to the receiving end. Image data, analyzing and displaying the encoded image data. [0003] Human vision and nervous system have different perceptions for different images. Human perception of images mainly includes perception of color and space in images. For example, for two different images, people’s perception of the two The degree of perception of color sense and sense of space in an image is different. Ther...
