Multi-duration Saliency Prediction with Implicit Representation learning

Dataset image

Description: Multi-duration saliency prediction is an important task in understanding temporal human visual attention. Previous methods [2,3] can only predict the saliency map at certain discrete timesteps, for example at 0.5s, 3s, 5s. Implicit neural representation learning shows very strong performance in modeling continuous functions. For example, it has achieved great success in 3d reconstruction, image/video super-resolution, talking face generation, etc. In this project, our goal is to develop a computational model to predict continuous human visual attention with implicit representation learning.

* Process the raw gaze data from our internal dataset GazeRecall to obtain the saliency ground truth * Follow [1] to develop a MLP-CNN based model for multiduration saliency prediction. * Evaluate the model performance.
