Need some help in certain .txt mean

So i was trying photometric stereo. And i m kinda confused with their "manual data folder" espesially obj_bbox.txt and probes_bbox.txt

Anyone can help me how to obtain these value?? ty so much

If u unzip PSBox-master, than open data u will find manual data folder that contain obj_bbox.txt and probes_bbox.txt. i m just confused how to obtain it with different object picture

Hi Pizzaa, I hope you know that the "manual" folder in the PSBox-master repository is provided as an example or template folder that contains some manually annotated data files for photometric stereo. It serves as a reference for understanding the format and content of the required files.

The "manual data" folder in the PSBox-master repository contains example files (“obj_bbox.txt” and “probes_bbox.txt”) that provide bounding box coordinates for the object and probes in the sample images provided with the dataset. Create a text file named “obj_bbox.txt” and save the bounding box coordinates for the object in the format: xmin ymin xmax ymax. Similarly, create a “probes_bbox.txt”.

If you want to automate the annotation process. Find the code below.

% Load object image
objectImage = imread('object_image.jpg');

% Display the object image and allow the user to draw a bounding box
figure;
imshow(objectImage);
title('Select bounding box for object');
objectBox = getrect; % Get the bounding box coordinates

% Save the object bounding box coordinates
objBBox = [objectBox(1), objectBox(2), objectBox(1) + objectBox(3), objectBox(2) + objectBox(4)];
dlmwrite('obj_bbox.txt', objBBox, ' ');

% Load probe image
probeImage = imread('probe_image.jpg');

% Display the probe image and allow the user to draw a bounding box
figure;
imshow(probeImage);
title('Select bounding box for probe');
probeBox = getrect; % Get the bounding box coordinates

% Save the probe bounding box coordinates
probeBBox = [probeBox(1), probeBox(2), probeBox(1) + probeBox(3), probeBox(2) + probeBox(4)];
dlmwrite('probes_bbox.txt', probeBBox, ' ');

Make sure you have the Image Processing Toolbox installed in your MATLAB environment to run this code.
