Abstract

The invention relates to a multi-probability combined prediction post-processing method and system for diatom detection and recognition and a storage medium. In the method, the method comprises the following steps: unifying overlapped sub-image prediction results to an original image space domain based on offset position information; and then, iteratively calculating the intersection ratio betweenthe prediction area with the maximum probability in the current prediction result and the remaining prediction area, calculating the average target area value of the prediction area meeting the condition, and taking the area on the original to-be-detected image corresponding to the area value as a diatom detection target. According to the post-processing method, the overall precision of diatom detection and recognition can be effectively improved, and the omission rate and the false detection rate are remarkably reduced.

Description

technical field [0001] The invention relates to the field of forensic examination, in particular to a multi-probability combination prediction post-processing method, system and storage medium for diatom detection and identification. Background technique [0002] In the field of forensic examination, diatoms detected in different visceral tissue samples (liver, kidney, lung, bone marrow) on corpses can effectively infer the cause and location of drowning. In the daily work of forensics, for micron-sized diatoms, microscopic imaging is usually carried out with high magnification, and then the detection and quantity statistics of diatom targets are carried out with the help of human eye recognition. The whole operation is complicated, time-consuming and inefficient. . The automatic detection and identification system of diatoms was proposed to solve the above problems. Its purpose is to automatically detect the position of diatoms from the scanned image of the sample tissue a...
