Target rapid extraction method based on microscopic light field model

The invention discloses a rapid target extraction method based on a microscopic light field model, which comprises the following steps: under a low-power objective lens, obtaining an image acquisition sequence, analyzing image texture complexity, obtaining a microscopic light field model graph, carrying out image segmentation on the image sequence based on the model graph, further extracting a region of interest in an image, and then extracting a target based on the extracted region of interest. The method comprises the following steps: extracting image features conforming to human visual habits from effective pixel percentage, gray scale, texture complexity, color difference degree, hollow rate, rectangularity, profile tolerance and side length ratio, performing image classification on each image acquisition point location, drawing a preliminary target region image, removing isolated single target point locations in the image, then removing invalid target regions, and obtaining a target region image; the met
