首先，MATLAB中image和imshow都可以用来图像显示，image函数的语法调用常有以下几种格式：image（A）；image（x,y,A）;其中，image（A）是将矩阵A 作为一个图像显示，A中的每一个元素都被指定一种颜色；image（x,y,A）其中的x,y分别表示显示图像左上角的坐标，其它与image（A）含义相同。当然image...

Image color data, specified in one of these forms: Vector or matrix — This format defines indexed image data. Each element of C defines a color for 1 pixel of the image. For example, C = [1 2 3; 4 5 6; 7 8 9];. The elements of C map to colors in the colormap of the as...

MATLAB® represents images as arrays (often two-dimensional matrices) in which each element corresponds to a single pixel in the displayed image. Working with images in MATLAB is similar to working with any other type of matrix data, and you can display any two-dimensional data as an image...

If you have a current version of MATLAB, theTiffclass provides a way to write multi sample image data. Note: This is a direct interface to LibTIFF, if you need more help, please look up the link in the code below: %% Write a 61x89x6 double matrix as a TIFF file ...
Since images can be represented by 2D or 3D matrices and the MATLAB processing engine relies on matrix representation of all entities, MATLAB is particularly suitable for implementation and testing of image processing workflows. The Image Processing Toolbox™(IPT) includes all the necessary tools fo...
Have them start with a letter and use underscores instead of dots. fn = {'v0_05', 'v0_10', 'v0_15', 'v0_20', 'v0_25', 'v0_30', ... 1 month ago | 0 Answered MATLAB will not open in MacOS Sequoia15.1 If you don't get an answer here today, then I suggest you cal...
I have nearly 300 binary images. I need to draw 12 red lines (whose start and end points are known) on every image directly into the matrix of the image without using imshow(). Please let me know if there is any way doing this?
