Abstract
An image processing method is performed by a computer, for determining that a line is a crack or something other than the crack. The method includes: extracting a linear region from an image of an object captured by an imaging apparatus; determining a luminosity change in a direction traversing the linear region at each of a plurality of positions separate in a longitudinal direction of the linear region; and identifying a type of the linear region based on the luminosity changes at the plurality of positions.
Claims12
A non-transitory computer-readable storage medium having stored therein a program for causing a computer to execute a process for image processing, the process comprising:
- extracting a linear region from each of a plurality of images of an object captured by an imaging apparatus, wherein the plurality of images are captured while light of different colors is respectively radiated toward the object;
- determining a luminosity change in a direction traversing the linear region at each of a plurality of positions separate in a longitudinal direction of the linear region of each of the plurality of images of the different colors;
- and
- identifying a type of the linear region based on a comparison between the luminosity changes of the different colors at each of the plurality of positions of the linear regions extracted from the plurality of images.
An image processing apparatus comprising:
- a memory storing an image of an object captured by an imaging apparatus;
- and
- a processor coupled to the memory and configured to execute a process including:
- extracting a linear region from each of a plurality of images of an object captured by an imaging apparatus, wherein the plurality of images are captured while light of different colors is respectively radiated toward the object;
- determining a luminosity change in a direction traversing the linear region at each of a plurality of positions separate in a longitudinal direction of the linear region of each of the plurality of images of the different colors;
- and
- identifying a type of the linear region based on a comparison between the luminosity changes of the different colors at each of the plurality of positions of the linear regions extracted from the plurality of images.
