Embodiment Construction
[0040] It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0041] Embodiments of the present application provide a speckle detection method, device, medium, and computer program product of an image. A test image is obtained based on the product to be tested, and pixel information of pixels in the test image is obtained. The pixel information includes the pixel The first pixel value of the point and the second pixel value group of the pixel point in the preset pixel area; based on the first pixel value and the second pixel value group in the pixel information, the speckle detection is performed on the test image to obtain A detection result; if the detection result is that there are spots in the test image, then determine the position of the spots based on the pixels. The present application can accurately determine whether there are spots in the test imag...

The invention discloses an image spot detection method and device, a medium and a computer program product, and the method comprises the steps: obtaining a test image based on a to-be-detected product, obtaining the pixel information of a pixel point in the test image, and enabling the pixel information to comprise a first pixel value of the pixel point and a second pixel value group of the pixel point in a preset pixel region; performing spot detection on the test image based on a first pixel value and a second pixel value group in the pixel information to obtain a detection result; and if the detection result is that the test image has the spot, determining the position of the spot based on the pixel point. Whether the test image has the spot or not can be accurately judged, the position of the spot is determined through the pixel points when the spot exists so as to determine the position of the abnormal point in the image sensor of the to-be-tested product, and the abnormal point in the image sensor of the to-be-tested product can be conveniently processed so that the quality of the image shot by the to-be-tested product can be improved.
Description
technical field [0001] The present application relates to the technical field of image processing, and in particular to an image speckle detection method, device, medium and computer program product. Background technique [0002] Most of today's electronic devices have camera functions for tasks such as face recognition and QR code detection, so the quality of cameras is crucial for such electronic products. However, during the manufacturing process of the camera's Camera Sensor (camera image sensor), abnormalities (such as defects or foreign objects) are prone to occur on the camera's image sensor, so that the image taken by the electronic device with this camera image sensor has spots. This results in poor quality, and it is currently impossible to accurately determine the location of the anomaly in the image sensor of the electronic device. Contents of the invention [0003] The main purpose of the present application is to provide an image speckle detection method, de...
