CodeJam is the largest annual hackathon run by the McGill Electrical, Computer, and Software Engineering Student’ Society (usually in our very own Trottier Engineering Building). 

CodeJam enables students to test their practical skills in a supportive, engaging, and, most of all, fun environment. Over the course of 36 hours, students will be challenged to brainstorm innovative ideas, to solve difficult problems, and to create an awesome prototype. All the while, students are supported by experienced mentors from companies such as your own. Our goal? To help give students the confidence and skills they need to own their professional growth, and to provide them with the industry connections necessary to accelerate that same growth.




If you applied to CodeJam, received an acceptance and also confirmed your attendance, you are eligible to attend CodeJam.

If you attended and participated at CodeJam, then you are eligible to make a submission. Each team must consist of no more than 4 participants.

Matrox: A Deep Learning Based Machine Learning Jorney with Matrox Imaging

Matrox Imaging division manufactures hardware and software components for the industrial machine vision industry. In the context of the Code.Jam 2020, our team wants to challenge you to solve a few Kaggle ( problems using our Matrox Imaging Library (MIL).
As an appetizer, we will walk you through our library and companion user interface by solving one of the Rock-Paper-Scissor classification competition available on Kaggle. You will be then ready to tackle the more complex suggested Kaggle challenges, and finally pick your own challenge!
Along the journey, you may want to develop your own short program to preprocess the images, for example. To maximize your creativity, feel free to combine the MIL with any other tool you may be familiar with, such as Python packages (ex. NumPy, Matplotlib, PIL, OpenCV, etc.)

Winners will be awarded a gift card.

Samasource-2: Online Retail and Shopping Smart App

Online Retail and Shopping Smart App. Retail and Shopping are increasingly “Digital by default”, and this trend has only gained traction in 2020. However, in the clothing/fashion sector, it is hard for shoppers to navigate all products that are available online, as keywords do not always convey what a piece of clothing looks like, or its style.
In this project, you will build an app to facilitate the shopping and product search experience, in whichever way you find useful. You will have access to an object segmentation machine learning model. This model will have been trained in advance on the iMaterialist dataset.

Winning team will be awarded $1000

Samasource-1: How to create an annotation system for 3D point cloud data using an immersive experience(vr)

LIDAR sensors paired to Machine learning models is a standard for self driving cars, it is now also becoming mainstream with mobile devices, customer appliances and gaming devices, often to enhance camera data with 3D information about its environment.
To build a Machine learning model from LIDAR data, training datasets have to be created. This is currently done via manual annotation of point cloud data by Annotators in a 2D desktop application.
This project is aiming at solving the complexity of 3D annotation by using a VR based application where an agent is immersed into the 3D world captured by the LIDAR sensor. The operator is able to navigate in this world as if they were part of the scene, through the VR application and draw bounding boxes around the various objects identified in the scene.

EchoAR: Virtual Reality & Augmented Reality App

Using echoAR's cloud AR/VR platform, build a project that can potentially solve COVID-19 related challenges.

Winning team will receive a 50$ Amazon gift card. Each team member will get 1-month free Business Tier access to EchoAR's platform and the winning project will be featured on echoAR's "Inspiration" Page.
