Abstract

The invention discloses a spatial life science experiment object semantic segmentation method and device and a storage medium. The method comprises the steps of determining an image category and a category score of an input image based on a category prediction model; generating a class activation graph based on the class score of the to-be-segmented image and the pixel gradient weight of each pixel in the last layer of convolution feature graph in the class prediction model; binarizing the class activation graph to obtain a coarse segmentation result of the to-be-segmented image; obtaining a guide back propagation graph of the to-be-segmented image; and taking the coarse segmentation result as an initial contour, taking the guide back propagation graph as a base graph to be fitted, and performing iterative evolution based on the level set to obtain a pixel-level semantic segmentation result of the image to be segmented. According to the method, high-precision pixel-level annotation information does not need to serve as the basis of strong supervised learning, semantic information is reserved, the segmentation precision can be effectively improved, reliable and powerful support is provided for experimental data analysis of scientists, and the data processing threshold is lowered.

Description

technical field [0001] The invention relates to the technical field of image data processing, in particular to a method, device and storage medium for semantic segmentation of experimental objects in space life sciences. Background technique [0002] Large spacecraft such as space stations are usually equipped with various types of space science payloads to carry out various space science experiments, involving space life science, microgravity fluid physics and combustion, etc. By studying the effects of microgravity on the growth and development of organisms, tissues, cells, proliferation and differentiation, space life science experiments help people understand and explore the growth and development laws of organisms in space, and lay the foundation for further space exploration and space utilization. In the process of scientists conducting space life science experiments, many cell images will be generated. Preprocessing these images, such as identifying the category of ce...
