Abstract
An image processing apparatus includes a measurement area setting unit that sets a measurement area in an input image, a small image setting unit that sets a small image in the input image based on the measurement area, a first estimation unit that estimates a flow distribution of a target in the small image, and a second estimation unit that estimates the number of targets to pass through the measurement area based on the flow distribution in the small image.
Claims17
An image processing apparatus comprising:
- a processor;
- and
- a memory storing executable instructions which, when executed by the processor, cause the image processing apparatus to perform operations including:
- setting a measurement area in an input image;
- setting a small image in the input image based on the measurement area;
- estimating a flow distribution of a target in the small image;
- and
- estimating the number of targets to pass through the measurement area based on the flow distribution in the small image,
- wherein the input image is divided into a plurality of small images with adjacent small images overlapping each other;
- a small image which is included in the measurement area is selected from the plurality of small images;
- and
- a number of targets to pass through the measurement area is estimated based on a flow distribution, which has been acquired from an area that does not overlap an adjacent small image as to the respective divided small images in the flow distributions.
An image processing method comprising:
- setting a measurement area in an input image;
- setting a small image in the input image based on the measurement area;
- estimating a flow distribution of a target in the small image;
- and
- estimating the number of targets to pass through the measurement area based on the flow distribution in the small image,
- wherein the input image is divided into a plurality of small images with adjacent small images overlapping each other;
- a small image which is included in the measurement area is selected from the plurality of small images;
- and
- a number of targets to pass through the measurement area is estimated based on a flow distribution, which has been acquired from an area that does not overlap an adjacent small image as to the respective divided small images in the flow distributions.
A non-transitory computer-readable storage medium storing a program for causing a computer to:
- set a measurement area in an input image;
- set a small image in the input image based on the measurement area;
- estimate a flow distribution of a target in the small image;
- and
- estimate the number of targets to pass through the measurement area based on the flow distribution in the small image, wherein
- the input image is divided into a plurality of small images with adjacent small images overlapping each other;
- a small image which is included in the measurement area is selected from the plurality of small images;
- and
- a number of targets to pass through the measurement area is estimated based on a flow distribution, which has been acquired from an area that does not overlap an adjacent small image as to the respective divided small images in the flow distributions.
