An image analysis method, a microscope video stream processing method, and a related apparatus. The method comprises: extracting a video frame of an image video stream, the medical image video stream comprising two or more frames of target object-based video frames (S202); extracting a single frame image feature of the video frame, and mapping same into a single frame diagnosis classification result (S204); and performing, on the basis of a video stream feature sequence, classification mapping to obtain a target classification result (S206), the video stream feature sequence comprising the single frame image feature of the video frames and the single frame classification result. Feature extraction and classification mapping are performed on the basis of the image video stream comprising two or more video frames, and information of the image video stream in a time dimension is reasonably utilized to obtain the target classification resu therefore, the accuracy of the classification result is improved, thereby providing an accurate basis for object classification.
