Face Parts Detection

25 May 2012 (Updated )

It detects faces with left eye, right eye, mouth, and norse.

Description

Run demo to try!
This code is implimented based on CascadeObjectDetector of FrontalFaceCART, LeftEye, RightEye, Mouth, and Nose.
I belive the performance is improved compared to the default usage of the face detection.
detectFaceParts and detectRotFaceParts are main functions.
detectFaceParts detects frontal faces with parts.
detectRotFaceParts detects faces with parts rotating an input image.

Each function has own help.

Please give full code for exact mouth and eyes detection and recognition (input will be an image).

Hi rizwan,

You can get the eye's region by my code. Please try to find the eye corner with that region.

Thanks.

Hello Massayuki Tanaka,

I am interested in extracting bounding boxs of left and right eyes. how I can extract it actually I am interested in eye corner detections by using standard detection techniques but I am facing difficulty in accessing eyes bounding box except nose and mouth. I have seen your reply that you have given on 24 july 2013 but it is not working in my case. I want to apply harris corner detection only on eyes. Please reply me on my email id: naqvirizwan@yahoo.com

Waiting for your kind reply.

Thanks in advance.

Hi Meenakshi,

My code does not provide the region of the forehead. But, you may be able to estimate rough the region of the forehead with eyes and face regions’ information.

Thanks.

Mr Tanaka
thanks for replying can u help me to find the forehead of facial image in your coding itself.I would like to share that it works with only using only these 3 files 'demo.m, buildDetector.m, decteFaceParts.m'

Hi Tanaka,

I have an issue with the code when I try to read gray scale sketches the error says:
Error using ShapeInserter/step
The Image input has 1 color planes and the Pts input has 1 shapes. The Color value(s) parameter must be a scalar.

Error in detectFaceParts (line 89)

Thanks for your response Tanaka!
Oh yeah, i got your point. When I tested your code for an image containing eyes only, it didn't work.
That means, this type of combination works when all the parts are present in the image. This is what hierarchical relationship I think.

Thanks.

04 Aug 2014 Masayuki Tanaka

Masayuki Tanaka (view profile)

Hi Sorath,

In my toolbox, I use a spatial correlation among a left eye, a right eye, a nose, and a mouse. I also use a hierarchical relationship between a face and face parts. I don’t think that a pistol and a rifle have such kind of spatial correlation. If there are some spatial correlation and/or the hierarchical relationship, you can combine multiple detectors for them by following my toolbox.

Thank you!

31 Jul 2014 Sorath Asnani

Hello Tanaka!
You have done a great job! This code has made life easier.
Can you tell me that where exactly in your code you have integrated multiple detectors?
Let suppose, if I have trained 2 custom detectors, one known as PistolDetector and the other as RifleDetector; can u guide me that how I can combine both the detectors?
Thanks.

Hello,Mr.Tanaka.

As I got,bbox is not an array of pixel coordiantes of rectangles.

Hi Bushry,
Thank you for your comment. I use the detectors which the computer vision system tool box provides in my code. Unfortunately, the computer vision system tool box does not provide the eye pair detector. I think that you need to build or learn the eye pair detector by yourself.

Hi Ooi, thank you for putting good rating!
I'm very sorry for late response. I also send email to you.

The detected face regions are cropped and scaled into "standard size" of the face detector. Then, each face part detectors are applied.

1. can you tell me how do these formula work?
Those formulas work to re-scale from the standard size to the original size and the position.

2. why want to set the stdsize is 176? is it any value is acceptable?
You can change the stdsize when you build the detector by the function of buildDetector. The default value of the stdsize is 176. I don’t have any theoretical reason to set 176. But, I think that value works well.

3. why the ratio formula is this type? is that possible change the ratio formula to other formula?
There might be some other formulations. But, the purpose of this calculation is just to return back to the original size and position. I don’t think that this formulation has technically special.

I hope this helps you. Thank you.

Hi, your code works great. But one thing that make me so confuse is the ratio type.
ratio = double(bbox(i,3)) / double(stdsize);
b(1,1) = (( b(1,1) + region(1,1) ) * ratio) + bbox(i,1);
b(1,2) = (( b(1,2) + region(2,1) ) * ratio) + bbox(i,2);
b(1,3) = b(1,3) * ratio;
b(1,4) = b(1,4) * ratio;

1. can you tell me how do these formula work?
2. why want to set the stdsize is 176? is it any value is acceptable?
3. why the ratio formula is this type? is that possible change the ratio formula to other formula?

Please reply me soon, thank you.

Hi sudha,
Yes, the information of the extracted eyes, noses and mouthes are stored in bbox.
% bbox: bbox(:, 1: 4) is bounding box for face
% bbox(:, 5: 8) is bounding box for left eye
% bbox(:, 9:12) is bounding box for right eye
% bbox(:,13:16) is bounding box for mouth
% bbox(:,17:20) is bounding box for nose
% please see the documentation of the computer vision toolbox for details of the bounding box.
