Methods for processing images to detect objects below the surface of the water

摘要

The present invention is a processing method to increase the detection of objects below the surface of the water comprising the steps of: acquiring image data in separate spectral regions simultaneously and converting the image data into intensity value arrays for each spectral region, transforming the intensity value arrays into two-dimensional discrete wavelet transform arrays for each spectral region, and subtracting in a pair wise manner the two-dimensional discrete wavelet transform arrays thereby obtaining images showing an object below the surface of the water.
