MATLAB Online에서 열기 테마복사 h = (1/(2*pi*sigma^2)).*exp(-(X.^2 + Y.^2)/(2*sigma^2)); hx = (-X/(sigma^2)).*h; kindly explain the following line especially what replicate and conv means here? 테마복사 fx = imfilter(img, hx, 'replicate', 'co...
MATLAB Online에서 열기 I tried to implement my own imfilter with 2D 5x5 Gaussian filter on gray scaled image, but I could not get the result. I am getting a fully white colored picture. Here is the myfilter. functionresult = myfilter(sourcepicture) ...
在matlab中,卷积可以由imfilter来实现,在opencv中则是由filter2D来实现。它们之间的具体转化过程是什么?我通过一系列实验来研究。 一、实验准备 为了方便观察,仍然是采用分开来研究的方法。1)是输入数字作为卷积内容,直接观察结果;2)是采用小块图片作为卷积内容,仍然是比较结果;3)是采用真实的图片和真实的卷积核作为...
The imfilter function computes the value of each output pixel using double-precision, floating-point arithmetic. If the result exceeds the range of the data type, then imfilter truncates the result to the allowed range of the data type. If it is an integer data type, then imfilter rounds fr...
卷积运算是图像处理和增强中经常遇到的一种算法。由于很多优秀的开源算法都是采用matlab编写的,在我改写为c语言的时候就必然会遇到改写卷积算法的问题。在matlab中,卷积可以由imfilter来实现,在opencv中则是由filter2D来实现。它们之间的具体转化过程是什么?我通过一系列实验来研究。

MATLAB Online에서 열기 Zhang, the difference is that there is a rotation of the kernel by 180 degrees (pi radians) between the two. So for: 테마복사 h = [1 2 3 4 5 6 7 8 9]; and 테마복사 h1 = [9 8 7 6 5 4 3 2 1]; x = randn(20,20); isequ...
