Weighted tensorized fractional Brownian textures
Céline Esser, Claire Launay, Laurent Loosveldt +1
This paper presents a new model of textures, obtained as realizations of a new class of fractional Brownian fields. These fields, called weighted tensorized fractional Brownian fie…
Measuring uncertainty in human visual segmentation
Jonathan Vacher, Claire Launay, Pascal Mamassian +1
Segmenting visual stimuli into distinct groups of features and visual objects is central to visual function. Classical psychophysical methods have helped uncover many rules of huma…
Flexibly Regularized Mixture Models and Application to Image Segmentation
Jonathan Vacher, Claire Launay, Ruben Coen-Cagli
Probabilistic finite mixture models are widely used for unsupervised clustering. These models can often be improved by adapting them to the topology of the data. For instance, in o…
Exact Sampling of Determinantal Point Processes without Eigendecomposition
Claire Launay, Bruno Galerne, Agnès Desolneux
Determinantal point processes (DPPs) enable the modeling of repulsion: they provide diverse sets of points. The repulsion is encoded in a kernel that can be seen as a matrix st…
