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.

This disclosure relates to stain unmixing of digital pathology images by determining initial color vectors associated with digital pathology stains (or chromogens) from pure color digital pathology images. The determined color vectors may be fine-tuned or adjusted to help improve stain unmixing performance. Adjustments may be performed via interfaces and / or automated techniques that perform adjustments to the color vectors based on actual multiplex images and one or more composite singleplex images. These adjusted color vectors may be further utilized for stain unmixing of a given multiplex image. Additionally, this disclosure provides techniques for generating multiplex images from one or more digital pathology images based on composite pixels and associated color vectors, recommended stains to be added to the multiplex image, and / or target color vectors.
