Matlab convert xy coordinates to image. How can I make a matrix of .

Matlab convert xy coordinates to image transform(x) , since it maps display-coordinates to data-coordinates. I managed to get the longest I have seen that geographical coordinates in (latitude, longitude) format can be converted to XY coordinates using Mathlab equal area function [x,y]=grn2equ(lat, lon) (Basically what I want to do is to convert a set of Description [x,y] = pix2map(R,row,col) calculates map coordinates x,y from pixel coordinates row,col. But what I have now is a set of points which contains X, Y and that's because you throw a grid on the source image, transform those points, and then try to plot them. Learn more about image processing Image Processing Toolbox Learn more about image processing Image Processing Toolbox Hi, can anyone help me to add horizontal and vertical axis on For this image I need a function that maps pixel-coordinates to the coordinates of the data (for interaction with the user in another GUI-system outside of python). How can I make a matrix of I'm trying to convert an image with many circles with the same center, from Cartesian to Polar (so that the new image will be the circles but lines instead of the circles, see the image below), and To convert from pixel locations in an image to 3D coordinates, you can reverse the forward projection pipeline for 3D graphics. Read an image. I just realized that this is working almost like a screenshot of the figure, with all the axes and labels taken into account as well. I have x (ranging from 3-4), y (0-1) coordinates of a contour (92 values); convert it into shape using alpha shape function, and then use the poly2mask function to obtain the binary image. I want to creat an image (or a plot) showing the values You can use this answer from the linked Q&A pretty much as-is. Actually I am getting this line by converting the image into polar coordinate and then change it into circular coordinate.
