内容提示: IEEE TRANSACTIONS ON ACOUSTIC, SPEECH, AND SIGNAL PROCESSING, VOL. ASSP-29, NO. 6, DECEMBER 1981 1153 Cubic Convolution Interpolation for Digital Image Processing ROBERT G. KEYS Absfrucf-Cubic convolution interpolation is a new technique for re- sampling discrete data. It has a ...
Bicubic interpolation is widely used in photo editing software for resizing images without losing quality and in digital cameras to enhance the quality of zoomed-in photos. It’s also employed in image transformation tasks, maintaining image quality during rotation, skewing, and other geometric adjustm...
Wavelet-based transformation techniques are widely used for performing image interpolation in the digital image processing. In this wavelet transform, a common assumption in the wavelet based image interpolation approach is that the input image is treated as the low frequency sub-bands of an unknown ...
and a digital zoom. A camera performs an optical zoom by moving the zoom lens so that it increases the magnification of light before it even reaches the digital sensor. In contrast, a digital zoom degrades quality by simply interpolating the image — after it has been acquired at the ...
(2) 用<<数字图像处理>>(Digital Image Processing,4th)(作者:Rafael C.Gonzalez)中的插值应用说明插值: 我们在缩放(zooming)、缩小(shrinking)、旋转(rotating)和几何校正数字图像时,要用到插值方法。要进行这些操作,基本上就是对图像进行重新采样。对于图像处理来说,插值(interpolation)是使用已知数据来估算未知位置...

Image and Video Processing: Interpolation is a technique that is often used in picture and video processing to boost image resolution or smooth out pixelated images. Numerical Analysis: Interpolation is frequently used in numerical analysis to resolve differential equations because it allows an equation...
