Image processing method, image processing apparatus, and image processing program
A region of interest extracting section automatically extracts regions of interest from within original images by obtaining the degree by which the features of portions within the original images differ from the features of surrounding portions, based on the colors of the original images, brightnesses of the original images, and the orientations of linear components that appear in the original images. A partial image generating section generates partial images by cutting out images of predetermined sizes that include the regions of interest, which are extracted by the region of interest extracting section, from the original images. The generated partial images are displayed.
1. An image processing apparatus, comprising:
an original image recording section, for recording original images;
a region of interest extracting section, for extracting regions of interest from within the original images, the regions of interest being regions at which new degrees of interest exceed a predetermined threshold value, wherein the region of interest extracting section calculates the new degrees of interest as a value which is obtained from combining, at a predetermined ratio, a degree of interest and a degree of reliability that a specified object is included in the original images, the degree of interest being obtained from a combination of the degrees to which the features of portions within the original images differ from the features of surrounding portions, based on the colors of the original images, brightnesses of the original images, and the orientations of linear components that appear in the original images;
a partial image generating section, for generating partial images by cutting out images of predetermined sizes that include the regions of interest, which are extracted by the region of interest extracting section, from the original images; and
a display section, for displaying the partial images, which are generated by the partial image generating section.
2. An image processing apparatus as defined in claim 1 , further comprising:
a command section, for selecting one of a plurality of generated partial images in cases that a plurality of generated partial images are generated, and for issuing a command to cause the selected partial image to be displayed by the display section.
3. An image processing apparatus as defined in claim 2 , wherein:
the partial image generating section generates the partial images based on the display resolution of the display section.
4. An image processing apparatus as defined in claim 3 , wherein:
the display section displays the partial images that include the region of interest in descending order of the new degrees of interest.
5. An image processing method, comprising the steps of:
recording original images;
obtaining a degree of interest from a combination of the degrees to which the features of portions within the original images differ from the features of surrounding portions, based on the colors of the original images, brightnesses of the original images, and the orientations of linear components that appear in the original images;
calculating new degrees of interest as a value which is obtained from combining, at a predetermined ratio, the degree of interest and a degree of reliability that a specified object is included in the original images;
extracting regions of interest from within the original images, the regions of interest being regions at which the new degrees of interest exceed a predetermined threshold value;
generating partial images by cutting out images of predetermined sizes that include the extracted regions of interest from the original images; and
displaying the generated partial images.
6. A non-transitory computer readable medium having recorded therein a program that causes a computer to execute an image processing method, comprising the procedures of:
recording original images;
obtaining a degree of interest from a combination of the degrees to which the features of portions within the original images differ from the features of surrounding portions, based on the colors of the original images, brightnesses of the original images, and the orientations of linear components that appear in the original images;
calculating new degrees of interest as a value which is obtained from combining, at a predetermined ratio, the degree of interest and a degree of reliability that a specified object is included in the original images;
extracting regions of interest from within the original images, the regions of interest being regions at which the new degrees of interest exceed a predetermined threshold value;
generating partial images by cutting out images of predetermined sizes that include the extracted regions of interest from the original images; and
displaying the generated partial images.
