1. An object detecting device comprising:
a feature extracting circuit configured to extract first feature data from an input image;
a feature transforming circuit configured to transform the first feature data into transformed feature data according to a transformation function; and
a decoder circuit configured to decode the transformed feature data into a region map indicating a detected object,
wherein the feature transforming circuit includes:
a transformation function generating circuit configured to generate the transformation function; and
a transforming circuit configured to transform the first feature data according to the transformation function to generate the transformed feature data, and
wherein the transformation function generating circuit includes:
a prototype data generating circuit configured to generate prototype data by using support feature data and a support label, the support feature data being the first feature data corresponding to a support image, the support label including foreground information and background information of the support image; and
a transformation function determining circuit configured to determine the transformation function by using reference data and the prototype data.
