Method and apparatus for filtering image colors, electronic device and storage medium

An electronic device, comprising a memory, a processor and a computer program stored in the memory and executable on the processor, wherein when the program is executed by the processor, the following steps are performed:

• acquiring an image to be filtered, wherein a pixel point in the image to be filtered is represented by a hue value, a saturation value and a value;
• acquiring a retaining proportion of the pixel point in the image to be filtered, wherein a retaining proportion of any pixel point is used to indicate a degree of a saturation of the pixel point to be retained, and is positively correlated with a similarity between a hue of the pixel point and a hue to be retained of the pixel point;
• and
• acquiring a filtered image by adjusting the saturation value of the pixel point in the image to be filtered based on the retaining proportion of the pixel point in the image to be filtered.

A non-transitory computer-readable storage medium storing computer instructions therein, wherein the computer instructions are configured to enable a computer to perform the following steps:

• acquiring an image to be filtered, wherein a pixel point in the image to be filtered is represented by a hue value, a saturation value and a value;
• acquiring a retaining proportion of the pixel point in the image to be filtered, wherein a retaining proportion of any pixel point is used to indicate a degree of a saturation of the pixel point to be retained, and is positively correlated with a similarity between a hue of the pixel point and a hue to be retained of the pixel point;
• and
• acquiring a filtered image by adjusting the saturation value of the pixel point in the image to be filtered based on the retaining proportion of the pixel point in the image to be filtered.
