  I would like to create a NxM white image. But how to put color vectors [256 256 256] into a 2D array?   NOTE:- Matlabsolutions.com  provide latest  MatLab Homework Help, MatLab Assignment Help  ,  Finance Assignment Help  for students, engineers and researchers in Multiple Branches like ECE, EEE, CSE, Mechanical, Civil with 100% output.Matlab Code for B.E, B.Tech,M.E,M.Tech, Ph.D. Scholars with 100% privacy guaranteed. Get MATLAB projects with source code for your learning and research. Try this to create a grayscale image:   whiteImage = 255 * ones(N, M, 'uint8'); imshow(whiteImage); To create an RGB image, try this: whiteImage = 255 * ones(480, 640, 3, 'uint8'); imshow(whiteImage);   SEE COMPLETE ANSWER CLICK THE LINK https://www.matlabsolutions.com/resources/how-to-create-a-white-image-.php

  I = imread('img.jpg'); I = (double(I).^3)   The problem is, when I do operations like I.^3, pixels go far away from 255 value. I need them to be in range 0 - 255, and be able to multiply image to any value, without exceeding range.   Anyone got idea how could I do it?   NOTE:- Matlabsolutions.com  provide latest  MatLab Homework Help, MatLab Assignment Help  ,  Finance Assignment Help  for students, engineers and researchers in Multiple Branches like ECE, EEE, CSE, Mechanical, Civil with 100% output.Matlab Code for B.E, B.Tech,M.E,M.Tech, Ph.D. Scholars with 100% privacy guaranteed. Get MATLAB projects with source code for your learning and research. You could use mat2gray() to map the min to 0 and the max to 1.   I = mat2gray(I); Multiply by 255 if you want in the range 0-255 and cast to uint8 if you want I = uint8(255 * mat2gray(I)); I would recommend using a more descriptive variable name than I. You don't want it to be mistaken for a 1 or an l, and you don't want

  I have black and white image data that is stored in a matrix, 'img'. When I execute the following commands, I can see the image in black and white:   imagesc(img); colormap(gray); However, when I try to display the image using 'imshow' or view a sequence of similar images using 'implay', all I see is a white image. Why can't I see the image data?   NOTE:- Matlabsolutions.com  provide latest  MatLab Homework Help, MatLab Assignment Help  ,  Finance Assignment Help  for students, engineers and researchers in Multiple Branches like ECE, EEE, CSE, Mechanical, Civil with 100% output.Matlab Code for B.E, B.Tech,M.E,M.Tech, Ph.D. Scholars with 100% privacy guaranteed. Get MATLAB projects with source code for your learning and research. Try checking the range of your image data.

This enhancement has been incorporated in MATLAB 7.5 (R2007b).   As a workaround in previous MATLAB releases, you can use the following MATLAB function to track mouse motion:     function mousetrk %MOUSETRK function to track mouse motion % This function creates two static text controls % which contain the x & y coordinates of the mouse % The driving callback is executed by the % WindowButtonMotionFcn of the figure. figure axes('Visible','off') xbox = uicontrol('Style','

  I have created a GUI with GUIDE, and I would like to let app users print an image of the app with a button. How can I do this?   NOTE:- Matlabsolutions.com  provide latest  MatLab Homework Help, MatLab Assignment Help  ,  Finance Assignment Help  for students, engineers and researchers in Multiple Branches like ECE, EEE, CSE, Mechanical, Civil with 100% output.Matlab Code for B.E, B.Tech,M.E,M.Tech, Ph.D. Scholars with 100% privacy guaranteed. Get MATLAB projects with source code for your learning and research. There are 2 approaches.   First, the easiest way is with the 'print' function. Call 'print' in the button callback, and it will get the current figure (which is the GUI) and print it.   For more fine-grained control over the printed image, use the following approach:     f = getframe(gcf); % Get an image of the app in pixel color values toShow = figure('Visible','off'); % Create a new invisible figure warning('off','images:initSize:a

  I have signal and i want to plot it's power spectral density , What should i do? is it right if i first calculate the FFT of a signal and then get the square abs of it's value?   NOTE:- Matlabsolutions.com  provide latest  MatLab Homework Help, MatLab Assignment Help  ,  Finance Assignment Help  for students, engineers and researchers in Multiple Branches like ECE, EEE, CSE, Mechanical, Civil with 100% output.Matlab Code for B.E, B.Tech,M.E,M.Tech, Ph.D. Scholars with 100% privacy guaranteed.

  I am receiving the following error when trying to use the "makehdr" utility.   low dynamic images must be RGB     I suspect the reason is that my images are black-and-white. Is there any workaround for this issue?   NOTE:- Matlabsolutions.com  provide latest  MatLab Homework Help, MatLab Assignment Help  ,  Finance Assignment Help  for students, engineers and researchers in Multiple Branches like ECE, EEE, CSE, Mechanical, Civil with 100% output.Matlab Code for B.E, B.Tech,M.E,M.Tech, Ph.D. Scholars with 100% privacy guaranteed. Get MATLAB projects with source code for your learning and research. "makehdr" works only on RGB images. The workaround for this issue is to convert the grayscale image to an RGB image. Grayscale images are 2D (m x n) matrices, while RGB images are 3D (m x n x 3) matrices. Therefore one must expand the 2D matrix to fill the 3D matrix. This can be accomplished a couple ways   1. Use REPMAT to replicate the 2D matrix 3 times.   % Step 1 - Lo
