1. An edge detecting device comprising:
a feature extracting circuit configured to extract first feature data and second feature data from an input image;
a prototype generating circuit configured to generate, using the first feature data and an input label, prototype data including foreground information of an object and background information of the object;
a region detecting circuit configured to generate a segmentation mask by detecting a region of the object using the first feature data and the prototype data; and
an edge extracting circuit configured to generate an edge map by combining the segmentation mask and the second feature data.
