Method and apparatus for automatically detecting and suppressing fringes, electronic device and computer-readable storage medium

An apparatus for automatically detecting and suppressing fringes, comprising:

• a processor;
• and
• a memory for storing instructions executable by the processor;
• wherein the processor is configured to:
• acquire an image shot by a camera and recognize a fringe of the image;
• acquire at least one fringe action parameter among shooting parameters of the camera based on a recognition result obtained by recognizing the fringe of the image;
• and
• perform a parameter adjustment on the acquired at least one fringe action parameter by adopting a parameter adjustment strategy matched with the acquired at least one fringe action parameter to perform fringe suppression on the image shot by the camera;
• wherein the processor is configured to acquire the image shot by the camera and recognize the fringe of the image by at least:
• acquiring the image shot by the camera, and construct a feature matrix matched with a detection area according to feature information of each pixel point within the detection area in the image;
• wherein, a matrix value of the each pixel point which is in the feature matrix and associated with the fringe is a first numerical value, and a matrix value of the each pixel point which is in the feature matrix and not associated with the fringe is a second numerical value;
• performing a convolution operation on the feature matrix and a preset fringe feature matrix;
• and
• determining that the fringe exists in the image based on a determination result that a convolution operation result satisfies a preset numerical condition.
