The present invention relates to a method for detecting a louse on a fish, comprising the steps of receiving an image of a fish; searching for pixels having colors within a background color interval and setting those pixels to a default pixel value; searching for pixels having colors within a fish surface color interval and setting those pixels to the default pixel value; and searching for a predetermined louse-shaped object in those parts of the image having a pixel value different from the default value. Then, the method comprises the step of determining if the predetermined louse-shaped object is found in the image. If it is found, the method is performing the steps of: providing a sub-image of the image, where the sub-image is containing the area of the image in which the predetermined louse-shaped object is found; and storing information about the sub-image, where the storing of information comprises storing information about the position of the sub-image in the image. |
