In contrast to existing datasets, all sequences are photometrically calibrated. We provide exposure times for each frame as reported by the sensor, the camera response function, and dense lens attenuation factors. We also propose a novel, simple approach to non-parametric vignette calibration, ...
In this paper, we present a per-pixel photometric calibration method that solves this problem. We measure the joint monitorcamera response function for every single camera pixel by displaying red, green, and blue screens at all brightness levels and capture them separately. These measurements are ...

Our technique does not require the visual hull or stereo reconstructions for bootstrapping and solely exploits image intensities without the need for radiometric camera calibration. We present results on real objects with varying degree of specularity and show that these can be used to create ...
Computer Science - Computer Vision and Pattern RecognitionWe conduct a thorough study of photometric stereo under nearby point light source illumination, from modeling to numerical solution, through calibration. In the classical formulation of photometric stereo, the luminous fluxes are assumed to be ...
While numerous point estimation methods have successfully determined photo- z , they often struggle with the inherently ill-posed nature of the problem and frequently overlook significant morphological features in the probability density functions (pdfs) of photo- z , such as calibration and sharpness...
Photometric stereo is a computer vision technique used to recover the surface normal at each pixel and the overall shape of an object based on three or more images of the same object captured under different lighting conditions. By analyzing how the brightness of each pixel changes across the ...
