Image processing method wherein an image is re-sampled and sharpened by subjecting the image to a convolution with a kernel, the elements of which are determined by selecting a first set of kernel values so that a convolution of the imag... D Meeussen,B Tytgat - US 被引量: 13发表: ...
5 However, if we save and update the sum of the input pixels in each of the three columns of the window (C1, C2, C3), the eight additions need to be computed only once at the beginning of an image line. The next output pixel is calculated as, Sign in to download full-size image...
Convolution can describe the diffusion of information, for example, the model of the diffusion that takes place if you put milk into your coffee and do not stir (pixels diffuse towards contours in an image). In quantum mechanics, it describes the probability of a quantum particle being in a ...

Image reconstruction by convolution with symmetrical piecewise nth-order polynomial kernels 来自 Semantic Scholar 喜欢 0 阅读量: 63 作者: Meijering, E.H.W.,Zuiderveld, K.J.摘要: The reconstruction of images is an important operation in many applications. From sampling theory, it is well known ...
This constructor is provided to allow the class to be initialized from an unarchiver (for example, during NIB deserialization). This is part of the NSCoding protocol. If developers want to create a subclass of this object and continue to support deserialization from an archive, they should imple...

imageconvolution( resource $image, array $matrix, float $div, float $offset): bool Applies a convolution matrix on the image, using the given coefficient and offset. 参数 image 由图象创建函数(例如imagecreatetruecolor())返回的 GdImage 对象。 matrix A 3x3 matrix: an array of three arrays of...
Thus, the typical procedure for obtaining the DFT of an image using the row–column decomposition is to 1. Obtain the 1-D FFT of each row, 2. Transpose the image and store it by columns, 3. Obtain the 1-D FFT of each column. If a convolution is to be performed, then the same ...
