Methods and systems for image processing and storage media thereof

A system, comprising:

• at least one storage device including a set of instructions;
• and
• at least one processor in communication with the at least one storage device, wherein when executing the set of instructions, the at least one processor causes the system to perform operations including:
• obtaining an image to be matched, the image to be matched including multiple pixel points;
• for each of the multiple pixel points,
• obtaining pixel reference information of the pixel point, the pixel reference information including first reference information related to a pixel gradient of the pixel point and second reference information related to pixel values of both the pixel point and adjacent pixel points of the pixel point;
• determining, based on the pixel reference information, whether the pixel point is a target pixel point, the target pixel point being a pixel point whose pixel value is not a preset value;
• in response to the pixel point being the target pixel point,
• determining an initial similarity between the target pixel point and a pixel point in a template image;
• and
• determining the similarity between the image to be matched and the template image based on at least one initial similarity corresponding to at least one target pixel point.

A non-transitory computer readable medium, comprising executable instructions that, when executed by at least one processor, direct the at least one processor to perform a method comprising:

• obtaining an image to be matched, the image to be matched including multiple pixel points;
• for each of the multiple pixel points,
• obtaining pixel reference information of the pixel point, the pixel reference information including first reference information related to a pixel gradient of the pixel point and second reference information related to pixel values of both the pixel point and adjacent pixel points of the pixel point;
• determining, based on the pixel reference information, whether the pixel point is a target pixel point, the target pixel point being a pixel point whose pixel value is not a preset value;
• in response to the pixel point being the target pixel point, determining an initial similarity between the target pixel point and a pixel point in a template image;
• and
• determining the similarity between the image to be matched and the template image based on at least one initial similarity corresponding to at least one target pixel point.
