IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD
First Claim
1. An image processing apparatus, comprising:
- a processed image generation unit configured to acquire an image around a vehicle picked up by a camera provided on the vehicle, and generate a processed image from the image for target object detection processing;
a provisional detection unit configured to scan a scanning frame of a predetermined size according to a detection target object on the processed image, and detect a plurality of position candidate regions of the detection target object within the processed image by determining a feature value for respective scanning positions using a dictionary of the detection target object; and
a final detection unit configured to determine an overlapping region of the plurality of position candidate regions, and determine a final detection position of the detection target object within the processed image based on the overlapping region and the plurality of position candidate regions.

Abstract
According to one embodiment, an image processing apparatus and an image processing method includes a processed image generation unit, a provisional detection unit, and a final detection unit. The processed image generation unit generates a processed image for detection processing from an image around a vehicle taken by a camera provided on the vehicle. The provisional detection unit scans a scanning frame of a predetermined size according to a detection target object on the processed image, and detects a plurality of position candidate regions of the detection target object within the processed image by determining a feature value for respective scanning positions using a dictionary of the detection target object. The final detection unit determines an overlapping region of the plurality of position candidate regions, and determines a final detection position of the detection target object within the processed image based on the overlapping region and the plurality of position candidate regions.
