In MATLAB, there is a very useful function called 'reshape', which can reshape a matrix into a new one with different size but keep its original data. You're given a matrix represented by a two-dimensional array, and two positive integers r and c rep
a = np.arange(2*4*4) b = a.reshape(1,4,4,2) #应该这样按反序来理解:最后一个2是一个只有2个元素的向量,最后的4,2代表4×2的矩阵,最后的4×4×2代表立体张量,第一个1代表只有一个这样的张量(即该张量在第四维度只有一个元素). c = a.reshape(2,4,4,1) #应该这样按反序来理解:最后一个1是只有一个1个元素的向量,最后的4,1代表4×1的矩阵(可降维成一个向量),最后的4×4×1代表立体张量(可降
图片中存在着色版的概念,二维矩阵的每个元素的值指定了一种颜色,因此可以显示出彩色. 迁移调色板 下述python代码将VOC数据集中的某个语义分割的图片的调色板直接应用在一个二维矩阵代表的图像上 #label_im is a numpy array of 1 x height x width #return an Image object,call its' save('out.png') functioin to save as image file def palette( label_im
