The goal of this research is to develop interpolation techniques which preserve or enhance the local structure critical to image quality, and preliminary results are presented which exploit either the properties of vision or the property of the image in order to achieve the goals.

Abstract

The goal of this research is to develop interpolation techniques which preserve or enhance the local structure critical to image quality. Preliminary results are presented which exploit either the properties of vision or the properties of the image in order to achieve the goals. Directional image interpolation is considered which is based on a local analysis of the spatial image structure. The extension of techniques for the design of linear filters based on properties of human perception reported previously to enhance the perceived quality of interpolated images is considered.>

A fast algorithm for two-dimensional median filtering based on storing and updating the gray level histogram of the picture elements in the window is presented, which is much faster than conventional sorting methods.

A new smoothing algorithm is proposed, which looks for the most homogeneous neighborhood area around each point in a picture, and then gives each point the average gray level of the selected neighborhood area, and has the ability to sharpen blurred edges.

A new class of edge-preserving noise-cleaning filters are introduced which use both spatial and nearest-neighbor constraints on image pixels to smooth an image.

A nonlinear interpolation scheme for image-resolution enhancement is presented that incorporates a hybrid local edge-fitting operator and produces an image of increased resolution with noticeably sharper edges and lower reconstruction error than produced by linear techniques.

The application of novel anisotropic filter design techniques based on properties of human vision to the processing of luminance and chrominance components of color images is considered and the image quality is substantially better than that of NTSC images for either sequential or composite techniques.
