High precision three-dimensional reconstruction and measurement of industrial objects by digital imagery is one of the most active research fields in Computer Vision and Digital Photogrammetry. Due to most of industrial sheet-metal parts are made up of linear features, it is important to extract lines from 2D images accurately. Meanwhile, quality of lines will further to decides on precision of reconstruction...
There is a need to develop automated methods to analyze images. A method that relies on the Helmholtz principle to discover edge features that is weakly dependent on the parameters is presented. An application of the Helmholtz principle requires a method of finding groups of independent and identically distributed random variables, and the fast level set transform was used to find such groups. The...
