[SpinBlur - 旋转模糊] Using the Spin Blur effect, you can rotate and blur the image around one or more points. The spin blur is a radial blur measured in degrees. Photoshop lets you work with center points, blur size and shape, and other settings, all wh…
本文利用 Python 实现PS 滤镜中的马赛克效果,具体的算法原理和效果可以参考之前的博客: http://blog.csdn.net/matrix_space/article/details/30469217 from skimage import img_as_float import matplotlib.pyplot as plt from skimage import io import random import numpy as np file_name='D:/Visual E…
本文用 Python 实现 PS 滤镜中的一种几何变换特效,称为扇形变换,将图像扭曲成一个扇形,具体的算法原理和效果图可以参考以前的博客: http://blog.csdn.net/matrix_space/article/details/46789467 import numpy as np from skimage import img_as_float import matplotlib.pyplot as plt from skimage import io import math im…
本文实现 PS 滤镜中的一种几何变换– Fish lens, 对图像做扭曲,感觉就像通过一个凸镜或者凹镜在观察图像一样. import numpy as np from skimage import img_as_float import matplotlib.pyplot as plt from skimage import io import math import numpy.matlib file_name2='D:/Visual Effects/PS Algorithm/4.jpg'…
本文用 Python 实现 PS 滤镜特效,Marble Filter, 这种滤镜使图像产生不规则的扭曲,看起来像某种玻璃条纹, 具体的代码如下: import numpy as np import math import numpy.matlib from skimage import io import random from skimage import img_as_float import matplotlib.pyplot as plt def Init_arr(): B = 256…
今天介绍一种基于高斯滤波和邻域随机采样,生成一种毛玻璃的图像特效,简单来说,就是先对图像做高斯滤波模糊,然后对模糊后的图像,通过对邻域的随机采样来赋予当前的像素点,这样,生成的图像有有一定的随机扰动和模糊,看起来就像隔着一层毛玻璃在观察图像一样. # -*- coding: utf-8 -*- """ Created on Sun Aug 20 11:03:53 2017 @author: shiyi """ import matplotlib.…
