I have a grayscale image and draw a colored scatter plot on it,but the colorbar just vary from blcak to white,i wanna know how to show the colorbar of the scatter plot but not grayscale image. 댓글 수: 0 댓글을 달려면 로그인하십시오. ...
image intensity values are equal to a constant. You can create a contour plot of the data in a grayscale image using theimcontourfunction. This function is similar to thecontourfunction in MATLAB®, but it automatically sets up the axes so their orientation and aspect ratio match the image...
Create Contour Plot of Image Data Read and display a grayscale image. I = imread("rice.png"); imshow(I) Create a contour plot of the image with three contour levels. imcontour(I,3); Input Arguments collapse all I—Grayscale image ...
1 灰度化(grayscale) 将彩色图像转化为灰度图像的过程称为图像灰度化。彩色图像中的像素值由RGB三个分量决定,每个分量都有0-255(256种)选择,这样一个像素点的像素值可以有1600万种可能(256256256),而灰度图的像素点的像素值是RGB三个分量值相同的一种特殊的彩色图像, 只有256种可能。所以在图像处理中,往往将各...
返回值的介绍:The return value A is an array containing the image data. If the file contains a grayscale image, A is an M-by-N array. If the file contains a truecolor image, A is an M-by-N-by-3 array. For TIFF files containing color images that use the CMYK color space, A is...

Which for my imageimshows: And you can also view this grayscale image using pseudocolors from a given colormap with something like: imshow(im,'Colormap',jet(255)) Which shows: But it’s not obvious how to use the colormap to actually retrieve the RGB values we see in the plot. Here...

Hi guys, i got a problem here where i want to put my picture into the GUI , and then change the RGB image into grayscale image, but somehow the grayscale image keep getting error and i dont how to fix it. Help please. Below is the coding that i had write, ...
Create a bar chart and export it as an image with "figure" padding. The gray border around the image outlines the captured region. bar(1:5) title("My Bar Chart") ax = gca; exportgraphics(ax,"figurepadding.png","Padding","figure") Positive number Include the specified amount of padding...
