The test cases can be found here and the results can be found here. NOTE: If you use any of the models, please do not forget to give proper credit to those providing the training dataset as well.

The code is heavily inspired by the OpenFace implementation. This training set consists of total of images over 10 identities after face detection. Some performance improvement has been seen if the dataset has been filtered before training.

Some more information about how this was done will come later. One problem with the above approach seems to be that the Dlib face detector misses some of the hard examples partial occlusion, silhouettes, etc.

This makes the training set too "easy" which causes the model to perform worse on other benchmarks. To solve this, other face landmark detectors has been tested.

One face landmark detector that has proven to work very well in this setting is the Multi-task CNN. Currently, the best results are achieved by training the model using softmax loss. A couple of pretrained models are provided. They are trained using softmax loss with the Inception-Resnet-v1 model.

Face Landmark Detection models form various features we see in social media apps. The face filters you find on Instagram are a common use case. The algorithm aligns the mask on the image keeping the face landmarks as base points. Please note! This blog teaches you to build a super simple face landmark detection model using Keras. For actual production models, this may not be useful. You can run the interactive Colab notebook in another tab to follow and understand each step. But here we have a problem.

Most images do not have a complete set of 15 points. So we need only those images whose 15 facial keypoints are with us. Using this scriptI have done a bit of cleaning and kept the modified data on my Dataset Archives GitHub repo.

The Colab notebook downloads the ZIP archive using the wget command. We also normalize the images as well as the coordinates keypoints. It contains 68 facial key points along with other features like age and gender. Give it try too!

Actually, I did some experiments with the model. We are using the Mean Squared Error as we are performing a regression task.

A small learning rate is always good if you have a good amount of data. Why are we using Batch Normalization layers? Read this blog to know more. We train the model for around epochs with a batch size of Note : Keep in mind the orientation of the input images.

Building from scratch: facial feature detection using CNN and tensorflow

The model trained on images that were rotated by 90 degrees could not generate correct predictions for an erect image. Pretty impressive right? You have just built a face landmark detection model right from scratch. In the notebook, I have included a code cell with which you can take an image with your webcam and run the model on it. I have published after a long time Meanwhile I was busy writing on Math…. Thanks for reading! Sign in.

When training PNet ,I merge four parts of data pos,part,landmark,neg into one tfrecord,since their total number radio is almost During training,I read 64 samples from pos,part and landmark tfrecord and read samples from neg tfrecord to construct mini-batch.

It's important for PNet and RNet to keep high recall radio. The format is:. Since the training data for landmark is less. I use transform,random rotate and random flip to conduct data augment the result of landmark detection is not that good.

Note that the models uses fixed image standardization see wiki. Removed a bunch of older non-slim models. Moved the last bottleneck layer into the respective models. Corrected normalization of Center Loss.

Added code to train a classifier on your own images. Added models where only trainable variables has been stored in the checkpoint.Face feature detection model forms various functions we see in social media applications.

The facial filter you find on instagram is a common use case. The mask is aligned on the imageand the facial feature is taken as the base point of the model. First, we need some data to train our model. We use the face image data set with marker features on Omri Goldstein kaggle. But here we have a problem. Therefore, we only need images with 15 facial keys.

With this script, I have done some cleaning and saved the modified data in dataset archives GitHub.

Colab notebook needs to use the WGet command to download the zip file. Download the dataset from Kaggle. Unzip the archive. Save all the processed data. We also standardized the image and coordinates key points. Tip: we found another dataset for face feature detection, called utkface. It contains 68 facial keys and other features, such as age and gender. Try it! I did some experiments on the model. The first model reads an image and passes it through a pre trained VGg network.

Next, the output of the VGg is flattened and passed through multiple fully connected layers. The problem is that even if the loss is small, the model can predict the same key points for each image.

The second model is one you can find in the colab notebook. Instead, we pass the image to the convolution layer and get the output in the shape of 1, 1, Therefore, the convolution layer provides us with output. With this model, the prediction value is different for each image or even the image outside the dataset!

BatchNormalization. We use mean square error MSE when performing regression tasks. If you have a lot of data, a smaller learning rate is always good. We trained the model about times, and the number of batches was After training, we will make some predictions on the test set. Note: remember the rotation angle of the input image. The model trained on the image rotated 90 degrees cannot generate correct prediction for the image not rotated.

If you have not modified the model and training parameters, the model after training should be as follows:. Impressive, right? You have just built a human face feature detection model from scratch. Pay attention to the official account. Path properties List all parent directories, parent directories, file or directory names, file prefixes, file suffixes, and so on from pathlib import Path […].
