Fast digital zooming system using directionally adaptive image interpolation and restoration

This paper presents a fast digital zooming system for mobile consumer cameras using directionally adaptive image interpolation and restoration methods. The proposed interpolation algorithm performs edge refinement along the initially estimated edge orientation using directionally steerable filters. Either the directionally weighted linear or adaptive cubic-spline interpolation filter is then se...

Directionally Adaptive Image Restoration

| A directional selective restoration method is described. The adaptivity is based on the estimation of the local SNR of the ideal image. In order to achieve directional adaptiv-ity, a directional selective transform, based on a discrete short time Fourier transform is presented. The results obtained are compared with a non-directional selective restoration method.

Image Zooming Using Radial Basis Fucntion Interpolation for Iris Recognition

Low resolution iris image can degrade the performance of iris recognition. A new iris image zooming method by using edge-directed image upsampling method based on radial basis function (RBF) interpolation [9] is proposed to restore a single iris image into a highresolution image. By increasing the resolution of iris image, we found that the performance of iris recognition was increased.

Image Restoration with Two-Dimensional Adaptive Filter Algorithms

Two-dimensional (TD) adaptive filtering is a technique that can be applied to many image, and signal processing applications. This paper extends the one-dimensional adaptive filter algorithms to TD structures and the novel TD adaptive filters are established. Based on this extension, the TD variable step-size normalized least mean squares (TD-VSS-NLMS), the TD-VSS affine projection algorithms (...

Robust Potato Color Image Segmentation using Adaptive Fuzzy Inference System

Potato image segmentation is an important part of image-based potato defect detection. This paper presents a robust potato color image segmentation through a combination of a fuzzy rule based system, an image thresholding based on Genetic Algorithm (GA) optimization and morphological operators. The proposed potato color image segmentation is robust against variation of background, distance and ...
