A Novel Resolution Enhancement Scheme Based on Edge Directed Interpolation using DT-CWT for Satellite Imaging Applications
نویسندگان
چکیده
Image resolution enhancement is a usable process for many image processing applications such as geoscience studies, astronomy and geographical information systems. Image interpolation is popularly used to increase the image resolution, but the potential problem associated with it is to magnify the image many times without loss in image clarity. Most of the classical linear interpolation techniques like bilinear & bi-cubic interpolation methods generate blurred images. By employing dual-tree complex wavelet transform (DTCWT) on a edge directional interpolation, it is possible to recover the high frequency components which provides an image with good visual clarity and thus super resolved high resolution images are obtained. The obtained simulation results comply with the above stated claim.
