This repository contains my projects for the Computer Vision Nanodegree.
This project is about defining and training a CNN to perform facial keypoint detection, and using computer vision techniques to transform images of faces. Facial keypoints (also called facial landmarks) mark important areas of the face: the eyes, corners of the mouth, the nose, etc. These keypoints are relevant for a variety of tasks, such as face filters, emotion recognition, pose recognition, etc. The model output is 68 keypoints, with coordinates (x, y), for that face, which I used later to add filters on the detected faces in an input live stream from a camera, running only on the CPU not the GPU without any delay in the feed.
Some results from my facial keypoint detection system:

In this project, I design and train a CNN-RNN (Convolutional Neural Network Encoder - Recurrent Neural Network Decoder) model for automatically generating image captions. The network is trained on the Microsoft Common Objects in Context (MS COCO) dataset. Trained only on 1 epoch the model reached an average loss= 2.007 and preplixity= 7.4. The model structure is described in the following image:
