1. An image processing apparatus for detecting pedestrians, the image processing apparatus comprising:
- a lane detecting module configured to extract a lane coordinate value from an input image; and
a pedestrian detecting module configured to set, as a pedestrian region of interest (ROI), a region between a first line passing through ends of first left and right lanes and a second line passing through ends of second left and right lanes which are respectively disposed above the left and right lanes, and search for the pedestrian ROI by using a predetermined window to detect a pedestrian region having a pedestrian feature,wherein the pedestrian detecting module divides the pedestrian region into an upper body region and a lower body region, and when the pedestrian feature is detected from at least one of the upper body region and the lower body region, the pedestrian detecting module detects the pedestrian region as a final pedestrian region.

Abstract
Provided is an image processing apparatus for detecting pedestrians. The image processing apparatus includes a lane detecting module configured to extract a lane coordinate value from an input image and a pedestrian detecting module configured to set, as a pedestrian region of interest (ROI), a region between a first line passing through ends of first left and right lanes and a second line passing through ends of second left and right lanes which are respectively disposed above the left and right lanes, and search for the pedestrian ROI by using a predetermined window to detect a pedestrian region having a pedestrian feature.

9. A pedestrian detecting method in an image processing apparatus, the pedestrian detecting method comprising:
-
extracting a lane coordinate value from an input image; setting a pedestrian region of interest (ROI) and a lane interval in the input image by using the extracted lane coordinate value; setting a search window by using the set lane interval; and detecting a pedestrian region in the set pedestrian ROI by using a pedestrian detection algorithm, wherein the setting of a search window comprises; setting a width of the search window by using the lane interval and a ratio variable used to calculate a width of a pedestrian from the lane interval; and setting a height of the search window by using the set width and a ratio variable between the width and a height of the pedestrian. - View Dependent Claims (10, 11, 12, 13)
