Edge Histogram Descriptor in Wavelet Domain Based on JPEG2000
Minyoung Eom, Yoonsik Choe · IEICE Transactions on Communications · 2007
Due to the decoding procedure and filtering for edge detection, the feature extraction process of MPEG-7 Edge Histogram Descriptor (EHD) is time-consuming and computationally expensive. We proposed the fast EHD generation method in wavelet domain of JPEG2000 images. Experimental results demonstrate the advantage of this method over EHD.
