This application discloses a method, apparatus, device, and storage medium for detecting off-color bright lines on a display panel based on CCD sensing, relating to the field of display panel detection technology. The method includes: acquiring an off-color image of the display panel under a preset color screen captured by the CCD imaging device; preprocessing the off-color image to obtain morphological feature images of different channels; performing line detection on each of the morphological feature images to obtain line feature information of different channels; and merging the line feature information of different channels to obtain a detection result. By employing multi-channel separation, morphological feature enhancement, and fusion detection techniques, this method solves the problems of uncertainty and weak contrast in existing detection methods when off-color bright lines appear under different color backgrounds, making stable identification difficult. Compared with existing technologies, it achieves high-sensitivity detection and precise positioning of off-color bright lines under different background colors, improving the accuracy and adaptability of the detection.

This invention relates to the field of image recognition, and more particularly to an image recognition method for the health status of marine aquaculture fish. First, based on the acquired raw RGB color image, instance-level segmentation is performed to obtain the category label, confidence score, and pixel-level binary mask for each fish instance. Based on the confidence score, a confidence score filtering process is performed. After obtaining the fish instances that pass the confidence score filtering, image preprocessing is performed to obtain a normalized color vector and a preprocessed RGB color image. Then, based on the normalized color vector and the preprocessed RGB color image, a posture-sensitive morphology-color joint health index extraction algorithm is used to obtain a health-sensitive feature index. Finally, based on the health-sensitive feature index, a judgment result is obtained. This method solves the technical problems of morphological indicators becoming ineffective due to fish posture distortion, the inability to quantify abnormal color features such as red spots and white spots, and the impact of fish species differences on the universality and accuracy of the assessment results.
