Linear Methods for Image Interpolation
We discuss linear methods for interpolation, including nearest neighbor, bilinear, bicubic, splines, and sinc interpolation. We focus on separable interpolation, so most of what is said applies to one-dimensional interpolation as well as N-dimensional separable interpolation. Source Code The source code (ANSI C), its documentation, and the online demo are accessible at the IPOL web page of this...
متن کاملImage Magnification based on Directed Linear Interpolation
The technology of computer graphics and digital cameras are prevalent. High-resolution display and printer are available. High-resolution images are needed in order to produce high quality display images and high quality prints for use in desktop publishing, large artistic printing, mobile phone etc. However, since high-resolution images are not usually provided, there is a need to magnify the ...
متن کاملAnalysis of Linear Interpolation Schemes for Bi-Level Image Applications
In the ofice. it is often ecessary to scan a picture at a certain resolution and then reproduce it at a different (usually higher) resolution. This conversion can be achieved by interpolating the scanned signal between the sample intervals. This paper discusses a class of linear interpolating methods based on resampling polynomial functions. In addition, we introduce new methods to compare the ...
متن کاملWarped distance for space-variant linear image interpolation
The problem of image interpolation using linear techniques is dealt with in this paper. Conventional space-invariant methods are revisited and changed into space-variant ones, by introducing the concept of the warped distance among the pixels of an image. A better perceptual rendition of the image details is obtained in this way; this effect is proved both via the evaluation of the response to ...
متن کاملAn Efficient Architecture of Extended Linear Interpolation for Image Processing
This paper presents a novel image interpolation method, extended linear interpolation, which is a low-cost and high-speed architecture with interpolation quality compatible to that of bi-cubic convolution interpolation. The method of reducing computational complexity of generating weighting coefficients is proposed. Based on the approach, the efficient hardware architecture is designed under re...
