% Create a detector object faceDetector = vision.CascadeObjectDetector;
% Read input image I = imread('visionteam.jpg'); This is the code given in Matlab hellp, can you suggest me how to crop the detected face and store it % Detect faces bbox = step(faceDetector, I);
% Create a shape inserter object to draw bounding boxes around detections shapeInserter = vision.ShapeInserter('BorderColor','Custom','CustomBorderColor',[255 255 0]);
% Draw boxes around detected faces and display results I_faces = step(shapeInserter, I, int32(bbox)); figure, imshow(I_faces), title('Detected faces');

I don't have the computer vision toolbox so I don't know how the face detector works. Does it not say in the documentation anything about box size? If not, call them and ask them.

Here is the code for 1- select image from a Location 2- detect faces in the selected image 3- Find the Location of Detected Faces 4- crop all detected faces on one Figure
%Code start
clc; [filename, filepath] = uigetfile ({'*.jpg';'*.bmp';'*.png'}, 'File Selector'); img = strcat(filepath, filename); img = imread(img); figure(1),imshow(img); FaceDetect = vision.CascadeObjectDetector; FaceDetect.MergeThreshold = 7 ; BB = step(FaceDetect,img); figure(2),imshow(img); for i = 1:size(BB,1) rectangle('Position',BB(i,:),'LineWidth',3,'LineStyle','- ','EdgeColor','r'); end for i = 1:size(BB,1) J= imcrop(img,BB(i,:)); figure(3),subplot(6,6,i);imshow(J); end
%Code End
if this Helped: Remember me in your Prayers
Thanks
