Unsupervised Local Plasticity in a Multi-Frequency VisNet Hierarchy
Mehdi Fatan Serj, C. Alejandro Parraga, Xavier Otazu
We introduce an unsupervised visual representation learning system based entirely on local plasticity rules, without labels, backpropagation, or global error signals. The model is…
Improving VisNet for Object Recognition
Mehdi Fatan Serj, C. Alejandro Parraga, Xavier Otazu
Object recognition plays a fundamental role in how biological organisms perceive and interact with their environment. While the human visual system performs this task with remarkab…
Aesthetics Without Semantics
C. Alejandro Parraga, Olivier Penacchio, Marcos Muňoz Gonzalez +2
While it is easy for human observers to judge an image as beautiful or ugly, aesthetic decisions result from a combination of entangled perceptual and cognitive (semantic) factors,…
SID4VAM: A Benchmark Dataset with Synthetic Images for Visual Attention Modeling
David Berga, Xosé R. Fdez-Vidal, Xavier Otazu +1
A benchmark of saliency models performance with a synthetic image dataset is provided. Model performance is evaluated through saliency metrics as well as the influence of model ins…
Modeling Bottom-Up and Top-Down Attention with a Neurodynamic Model of V1
David Berga, Xavier Otazu
Previous studies suggested that lateral interactions of V1 cells are responsible, among other visual effects, of bottom-up visual attention (alternatively named visual salience or…
Psychophysical evaluation of individual low-level feature influences on visual attention
David Berga, Xosé Ramón Fdez-Vidal, Xavier Otazu +2
In this study we provide the analysis of eye movement behavior elicited by low-level feature distinctiveness with a dataset of synthetically-generated image patterns. Design of vis…
