Abstract
Provided is a method of detecting a pedestrian through feature information prediction based on an integral image. The method includes extracting a feature image of an obtained original image; generating an integral image of the feature image; predicting an integral image of an enlarged/reduced feature image using the integral image of the feature image and an image enlargement/reduction scale value; and detecting a pedestrian using an integral image of the predicted enlarged/reduced feature image. Accordingly, it is possible to decrease a time taken for a feature extracting operation, and perform pedestrian detection efficiently.
Claims12
A method of detecting pedestrians, the method comprising:
- extracting a first feature image of a first image;
- generating a first integral image of the first feature image;
- calculating and predicting a second integral image of a second feature image using a scale value and the first integral image;
- and
- detecting a pedestrian using the second integral image,
- wherein the second feature image is either enlarged or reduced in size compared to the first feature image, and wherein the scale value is a size ratio between the first feature image and the second feature image.
A computer readable recording medium recording a computer program for performing a method of detecting pedestrians, the method comprising:
- extracting a first feature image of a first image;
- generating a first integral image of the first feature image;
- calculating and predicting a second integral image of a second feature image using a scale value and the first integral image;
- and
- detecting a pedestrian using the second integral image,
- wherein the second feature image is either enlarged or reduced in size compared to the first feature image, and wherein the scale value is a size ratio between the first feature image and the second feature image.
