Choice 3: Sketches

Choice 3: Sketches#

In this project, you will develop a content-based image retrieval system with PyTorch. You will focus on the case where the query is a hand-drawn sketch, and the goal is to find photos that match the category of the object depicted in the sketch. You will build a neural network that learns a similarity metric between sketches and photos, allowing the system to retrieve images from a photo gallery based on how well they visually correspond to the query sketch.

Convolutional Networks, Transfer Learning, Weak Supervision

Requirements: This project can be completed on a standard laptop without a dedicated GPU. However, having access to a GPU will allow you to choose a larger pre-trained model (e.g., ResNet-50) and fine-tune it for potentially better performance.
