Abstract
Provided are an image detection device, an image detection method and a program, which are capable of improving correspondence to a target deformation by optimizing a template shape, when performing target detection using template matching. An image detection device 100 for detecting a target from an input image comprises: a template generation unit 10 that generates a template for detecting a target; a mask generation unit 20 that generates a mask which shields a portion of the template, on the basis of temporal variations of a feature point extracted from an area including the image target; and a detection unit 30 that detects the target from the image using the template a portion of which is shielded by the mask.
Claims12
An image detection device comprising:
- at least one memory that stores a set of instructions;
- and
- at least one processor configured to execute the set of instructions to:
- generate a template for detecting a target;
- divide an area in an input image into subregions, the area including the target;
- extract centers of the subregions as feature points;
- generate a mask partly shielding the template based on temporal variation of the feature points;
- and
- detect the target from the image by using the template partly shielded by the mask.
An image detection method comprising:

- extracting centers of the subregions as feature points;
- generating a mask partly shielding the template based on temporal variation of the feature points;
- and
- detecting the target from the image by using the template partly shielded by the mask.
A non-transitory computer readable storage medium storing a program causing a computer to execute:
- template generation processing of generating a template for detecting a target;
- tracking processing of dividing an area in an input image into subregions, the area including the target;
- extraction processing of extracting centers of the subregions as feature points;
- mask generation processing of generating a mask partly shielding the template based on temporal variation of the feature points;
- and
- detection processing of detecting the target from the image by using the template partly shielded by the mask.
