  Hello everybody i am writing a Program using C++ with OpenCV library! and I am using a function generated by Matlab Mex which takes an image and returns values! it look something like this   array=findsomething(image);//matlab function the image is a OpenCV variable which called Mat! this Mat stores the pixels in a unsigned char array as BGR. while Matlab function stores the pixels in RGB array. converting the data between the OpenCV variable and the Matlab Function variable means copying each pixel from the first variable Mat into Unsigned Char *array(this is the Matlab function Variable) which takes a really long time for each i call an image from the camera. is there a way to change how Matlab stores and handles the image data to become BGR ?

Hi,   I stuck at my study now.   I have one example image.   From this image, I would like to separate these five small objects in the picture to be five small images.   How can I do this. I need your help please.   I am looking forward to hear from you. Thank you very much.

  I want to create the .mat file in which I need to store the Colour images and corresponding each colour image I need to store 4 histograms in row form. Can any one help me with code how to store color image and corresponding histogram in row form?     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.

  Hello, i am trying to make a bode plot of the transfer function of a twin-t notch filter, that i am analyzing. I was able to produce the transfer function, and the bode plot by hand, but i am struggling to do it in Matlab, here is what i have so far: r=320; %Resistance c=100*10^-9; %Capactiance p=(1/(r.*c)); %Beta a=0.95; %Signma, adjusts the wiper of a potentiometer f=(5000); %Target Frequency s= (1i*f); h=((s^2 + p^2) ./ (s^2+4*p*s*(1-a)+p^2)); %Transfer function mh=abs(h); %Magitude of h ah=angle(h); %Phase angle of h, in rads. I am trying to plot the body function, and here is one i made for the transfer function H=2/(s+1):   % Example Transfer Function: g(s) = 2/(s+1) % Numerator num = [2]; % Denominator den = [1 1]; % Transfer Function G = tf(num, den) % Plot Frequency Response bode(G), grid   My question is, how would i represent the numerator and the denominator, since they are both powers of of s, which from my understanding the computer understands as s=jw, and thus i

  Hi, I would like to make a stem diagram where drop lines are horizontal and not vertical. Even better would be if ML is able to plot horizontal vectors from a baseline of y-axis.   Actually what I'm trying to plot is velocity profile in pipe.

I suggest you to use   quiver  function:   y = 0:10; u = 25-(y-5).^2; quiver(0*y,y,u,0*u) Of course you can do it with stem function: x = 0:10; y = 25-(x-5).^2; stem(x,y) view(90,90)     SEE COMPLETE ANSWER CLICK THE LINK https://www.matlabsolutions.com/resources/how-to-solve-stem-problem-.php

  I have a base plot in which I would like to add a smaller version of a second plot/figure ontop of the base plot at a certain location.   The second plot (or figure) is already saved as a .fig file. How do I import the .fig file and its data and plot it as is but smaller (so it fits inside the base plot without hiding base plot data) onto the base plot?

Second, create a second set of axes and plot. Here is an example of getting children of current axes and plotting the data on a s
