This paper presents another approach to segmenting a scene of rocks on a conveyor belt for the purposes of measuring rock size. Rock size estimation instruments are used to monitor, optimize and control milling and crushing in the mining industry. We propose a joint analysis of range and intensity images of rocks where sections extracted from range images are used to guide a Model-driven intens...

Algorithms for shape offsetting are of great importance in computer-aided design (CAD), computer-aided manufacturing (CAM), the numerical control (NC) of machines, computer graphics and related fields. The need for offset shapes arises in applications such as the numerical control of sawing machines or milling machines in the car industry. The problem of shape offsetting can be formulated as fo...
