Automatic classification of zooplancton by image analysis

ICASSP '86. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005
Automatic identification and counting of zooplankton is becoming very useful in marine ecology to avoid long and tedious tasks for biologists. We propose a method of image analysis to detect edges, filter the binary image to reduce spots and appendices such as legs or antennas, and measure parameters, such as the length of the abdomen which are finally
