3-D Shape Identification System Using Bright Spots Matrix

3-D shape approximation using parametric geons

This paper presents a new approach to 3D shape representation { approximating the shapes of object parts by a set of prescribed volumetric models using single-and multi-view range data. We deene a new set of volumetric part models , called parametric geons. These are seven qualitative shapes, each of which is formulated by a restricted globally-deformed superellipsoid. Model recovery is perform...

Sample-space bright spots removal using density estimation

Rendering images using Monte-Carlo estimation is prone to bright spots artefacts. Bright spots correspond to high intensity pixels that appear when a very low probability sample outweighs all other sample contributions. We present an average estimator that is robust to outliers, which detects and removes samples that are considered as outliers, and lead to bright spots in images computed using ...

3-D Shape Reconstru

We present a method for 3-D shape reconstruction of retinal fundus from fluorescein images. Our method extracts the location of vessels’ bifurcation as a reliable feature for estimating the epipolar geometry using a plane-and-parallax approach. The proposed solution robustly estimates the fundamental matrix for nearly planar surfaces, such as the retinal fundus. We propose the use of mutual inf...

Bright spots of sustainable shark fishing

Sharks, rays and chimeras (class Chondrichthyes; herein 'sharks') today face possibly the largest crisis of their 420 million year history. Tens of millions of sharks are caught and traded internationally each year, many populations are overfished to the point where global catch peaked in 2003, and a quarter of species have an elevated risk of extinction [1-3]. To some, the solution is to simpl...
