Abstract
An image analysis device includes: an acquisition unit to acquire an input image; a detection unit to analyse the input image acquired by the acquisition unit and to detect an area corresponding to a component image constituting the input image and a type of the component image; an expansion unit to expand the area detected by the detection unit; an evaluation unit to evaluate an image included in the area expanded by the expansion unit on the basis of a rule according to the type; and an output unit to output the area corresponding to the component image from the area expanded by the expansion unit on the basis of an evaluation result given by the evaluation unit.
Claims9
An image analysis device comprising processing circuitry configured
- to acquire an input image;
- to analyze the acquired input image and to detect an area corresponding to a component image constituting the input image and a type of the component image;
- to expand the detected area one or more times until an exit condition is satisfied, the exit condition being one of an expansion area included in the expanded detection area including an area of a different type from the type of the detection area, a number of the expansions of the detection area reaching a maximum limit, the expansion area enclosing the outline of the component image;
- to evaluate an image included in the expanded area on the basis of a rule according to the type;
- and
- to output the image included in the expanded area as an image corresponding to the component image on the basis of an evaluation result obtained.
A non-transitory storage medium storing an image analysis program to make a computer execute processes of:
- acquiring an input image;
- analyzing the acquired input image and detecting an area corresponding to a component image constituting the input image and a type of the component image;
- expanding the detected area one or more times until an exit condition is satisfied, the exit condition being one of an expansion area included in the expanded detection area including an area of a different type from the type of the detection area, a number of the expansions of the detection area reaching a maximum limit, the expansion area enclosing the outline of the component image;
- evaluating an image included in the expanded area on the basis of a rule according to the type;
- and
- outputting the image included in the expanded area as an image corresponding to the component image on the basis of an evaluation result obtained.
