Abstract

The invention relates to the technical field of computer vision, and particularly discloses a low-redundancy rapid reconstruction method for a plankton hologram comprising the following steps: S1, collecting a plankton digital hologram, and generating a source image data set; S2, calibrating plankton in each holographic source image in the source image data set to obtain a calibration data set; S3, training the established hologram reconstruction network by using the calibration data set, and testing the trained hologram reconstruction network by using the source image data set; and S4, using the tested hologram reconstruction network for reconstruction of other plankton holographic source images. The hologram reconstruction network can automatically detect an effective target area and reconstruct an area of interest. Compared with a traditional numerical reconstruction method, the hologram reconstruction network trained by the method is high in plankton hologram reconstruction speed and high in redundant information elimination efficiency, and is expected to play an important role in marine environment detection.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a low-redundancy fast reconstruction method of plankton holograms. Background technique [0002] The ocean plays an important role in regulating the earth's climate and maintaining the global life system. As an important part of the marine ecosystem, plankton plays an indicative role in climate change and changes in the marine ecological environment. Holographic imaging technology has become an important tool for ocean analysis and is used in the detection of marine plankton. Reconstructing the hologram can obtain information such as the state of plankton, particle size spectrum, etc., and provide information for ocean monitoring. Because the effective objects in the source image dataset are sparse and there is a lot of noise. Traditional numerical reconstruction methods need to scan and reconstruct different diffraction depths, and then perform effective target detect...
