Device, method, and computer program product for detecting object

A method for detecting an object, the method comprising:

• detecting an object to be detected with respect to a frame image that constitutes input moving image data, with a first algorithm for searching for an area having a feature value similar to a feature value of the object by learning;
• determining whether a travel based on movement of the object is smaller than a threshold;
• setting, when the travel is smaller than the threshold, a second detection area inside a first detection area in which the object is detected with the first algorithm, the second detection area being smaller in size than the first detection area;
• and
• detecting, when the travel is smaller than the threshold, the object in the second detection area with a second algorithm for searching without learning for the movement destination of a feature area in the frame image.

A computer program product having a non-transitory computer readable medium including programmed instructions, wherein the instructions, when executed by a computer, cause the computer to perform:

• detecting an object to be detected with respect to a frame image that constitutes input moving image data, with a first algorithm for searching for an area having a feature value similar to a feature value of the object by learning;
• determining whether a travel based on movement of the object is smaller than a threshold;
• setting, when the travel is smaller than the threshold, a second detection area inside a first detection area in which the object is detected with the first algorithm, the second detection area being smaller in size than the first detection area;
• and
• detecting, when the travel is smaller than the threshold, the object in the second detection area with a second algorithm for searching without learning for the movement destination of a feature area in the frame image.
