- 21 August 2020 Product detection in movies and TV shows using machine learning – part 5: Finding sweeties quick
In Part 4, I made a start with establishing a new training dataset by harvesting publicly accessible photos on social media. The main benefit of using user generated content is that they were taken in a real-world setting, hence close to what the targeting logos would look like in a film. For con...
- 22 May 2020 Smart Campus project – part 3 (COVID-19) – in progress – [10 June 2020]
I have been playing with the project data to study the impact of COVID-19 social distancing / lockdown to the university, especially the use of campus facilities. Meanwhile there are some time series analysis and behavioural modelling that I’d like to complete sooner than later. Everything has ta...
- 26 March 2020 Product detection in movies and TV shows using machine learning – part 4: Start a new dataset
Public image datasets are very handy when it comes to ML training but at some point you’ll face a product/logo that are not covered by any existing dataset. In our case, we are experimenting with detecting Cadbury Roses and Cadbury Heroes products. We need to construct an image dataset to cover t...
- 25 March 2020 Product detection in movies and TV shows using machine learning – part 3: Training and Results
Training has been an ongoing process to test what configurations work for our us the best. Normally you set the training config, dataset and validation strategy then sit back and wait for the model performance to peak. Figures below show plots of loss and mAP@0.5 for 4000 iterations of training w...
- 24 March 2020 Product detection in movies and TV shows using machine learning – part 2: Dataset and implementations
Dataset for training Existing object detection models are most trained to recognise common everyday objects such as dogs, people, cars, etc. We’ll use these pre-trained models later on when we do scene/character detection. For logo detection, we need to train out own model for the logos we need t...
- 23 March 2020 Product detection in movies and TV shows using machine learning – part 1: background
This blog series discusses some R&D work within an ongoing “Big Idea” project. The project is in collaboration with the Big Film Group Ltd , a leading Product Placement Agency working with Blue Chip clients across UK and International entertainment properties. Background Currently as part of the ...
- 27 January 2020 AI and generative art
The new year started with a couple of interesting projects on AI. In a HEIF-funded “Big Ideas” project, I am working with a brand placement company to prototype a solution that uses computer vision and deep learning to automate the evaluation of how brands and products appear in movies and TV sho...
