Sensory representations optimized for the natural environment
… systematically explore how different aspects of natural stimulus statistics can impact and determine perceptual behavior and sensory representation in both biological and artificial systems. In Chapter 1, I provide a brief review of the theory of efficient coding, models of natural image …

High-level visual object representation in juvenile and adult primates
… networks (CNNs). We then describe a set of natural image statistics automatically incorporated into high-performing CNNs from supervised training-it is possible primate development incorporates these or similar natural image statistics into its synaptic strengths. Finally, we describe the …

Surface reflectance recognition and real-world illumination statistics
… photograph is difficult because the observed image depends heavily on the amount of light incident from every direction. A mirrored sphere, for example, produces a different image in every environment. To make matters worse, two surfaces with different reflectance properties could produce …

Efficient inference and learning for computer vision labelling problems
… towards the era of large videos and gigapixel images, computational efficiency is becoming increasingly important. We present two novel methods to improve the efficiency of energy minimization algorithms. The first method works by "recycling" results from previous problem instances. The second …

Generation and analysis of segmentation trees for natural images
… use of the structure and hierarchy present in images. We develop a new low-level, multiscale, hierarchical image segmentation algorithm designed to detect image regions regardless of their shapes, sizes, and levels of interior homogeneity. We model a region as a connected set of pixels that is …
