Improving Edge-Based Feature Extraction Using Feature Fusion

Feature extraction is arguably the most important stage of an automatic object detection system. It is in this stage where the results of previous processing steps are interpreted to somehow characterize an object. Developing methods for feature extraction and feature vector generation using information from edge maps is a natural progression, as edge detection determines structure in images. A new edge-based feature extraction scheme is introduced based on the feature fusion of two existing methods. A generalized set of kernels for edge detection is also presented. The experimental results show that the detection of different objects of interests is improved using the new method.
