Object recognition and computer vision 2020

Class webpage: http://www.di.ens.fr/willow/teaching/recvis Grading:

• 3 programming assignments (50%)
• Instance-level recognition
• Neural networks
• Image classification competition
• Final project (50%)

More independent work, resulting in a report and a class presentation.

Assignments are strictly individual Copy-paste of the code, results, parts

• f the report

0p. FPs can be done in groups of max 2 people Policy

Assignment I: Instance level recognition

• Part I: Sparse features for

matching specific objects in images ○ Feature detector and descriptor ○ Robust match filtering techniques

• Part II: Compact

descriptors for image retrieval

Assignment II: Neural networks

• Part 1: Neural Network’s theory:

−

Forward pass, Backward pass

−

Parameter update

• Part 2: Building blocks of convolutional neural networks
• Part 3: Training a CNN on CIFAR-10 dataset with PyTorch

Assignment III: Image Classification Competition

• Bird image classification
• Class Kaggle competition

Final project

• Can be done individually or as a group of max 2 people
• The proposed project topics are from the recent top-conference

publications in computer vision, see example topics from 2019 here: http://www.di.ens.fr/willow/teaching/recvis19orig

• Student-defined projects are welcome
• Final project can be joint with another MVA course
• We plan to arrange $100 Google Cloud credits for the project

○ This will be announced through Moodle before projects start

• Select the topic + write project proposal
• Present the work in the class
• Write project report

• Sign up for the course with your school account via
