Claim 0:
1. A method for counting aquatic creatures, comprising:
providing a plurality of flow channel images of a flow channel, wherein the flow channel images correspond to a plurality of image capturing time points in a one-to-one manner;
defining a scan line in each of the flow channel images, wherein the scan line corresponds to a plurality of scan line pixels in each of the flow channel images;
performing a binarization process on the scan line pixels in each of the flow channel images to obtain a plurality of binarized pixel data sets, wherein the binarized pixel data sets correspond to the flow channel images in a one-to-one manner;
determining a plurality of aquatic creature range data sets in accordance with the binarized pixel data sets, wherein the aquatic creature range data sets correspond to the flow channel images in a one-to-one manner, and each of the aquatic creature range data sets comprises at least one aquatic creature position data set, and the aquatic creature position data set includes a start position of aquatic creature and an end position of aquatic creature;
determining identification and moving direction information of aquatic creature corresponding to each of the aquatic creature range data sets in accordance with the aquatic creature range data sets; and
determining a number of aquatic creatures passing through the scan line in accordance with the identification and moving direction information of aquatic creature corresponding to each of the aquatic creature range data sets.
