Title:
画像処理装置及びプログラム
Document Type and Number:
Japanese Patent JP5742399
Kind Code:
B2
Abstract:
An image processing apparatus includes the following elements. A line-candidate identifying unit identifies candidates of lines that constitute a contour of a subject region, on the basis of a captured image. A line-probability calculating unit calculates, for each identified candidate, line probability information representing a probability that the candidate is a line that constitutes the contour of the subject region, on the basis of feature values of positions located at or within a reference distance from the candidate in the captured image. A region-probability calculating unit calculates region probability information representing a probability that a target region surrounded by a predetermined number of candidates chosen from the identified candidates is the subject region, on the basis of the line probability information of the predetermined number of candidates. A subject-region detecting unit detects the subject region, on the basis of the calculated region probability information.
