convert binary map from pixel to geometric

if i have the binary map bellow

How can represent it in geometric coordinates

Hi Mohammed,

As per my understanding, you are trying to extract geometric coordinates of rectangles from an RGB JPEG image using MATLAB. To achieve this, you will need to convert the image to grayscale, create a binary mask using thresholding, and then use the MATLAB function “regionprops” to obtain properties like “BoundingBox” and “Centroid”.

For further guidance, you can refer to the following resources:

• Read images in MATLAB: https://www.mathworks.com/help/matlab/ref/imread.html
• Convert to grayscale: https://www.mathworks.com/help/matlab/ref/rgb2gray.html
• Logical operations for creating binary masks: https://www.mathworks.com/help/matlab/logical-operations.html
• Extract region properties: https://www.mathworks.com/help/images/ref/regionprops.html

Additionally, the "Threshold Intensity Values" section under Chapter 3 of the MATLAB Onramp provides an excellent explanation of intensity thresholding: https://matlabacademy.mathworks.com/details/image-processing-onramp/imageprocessing

Hope this helps!
