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...
Texture mapping and large-scale orthophoto mosaic are important in city 3D-model reconstruction. For some factors such as illumination direction and imaging time, in the course of obtaining images, there is often an obvious holistic color shift for imaging processing in the natural light, especially for remote sensing images and aerial images. The color of the overlapped areas in the two adjoined...
We present an image segmentation algorithm based on inscribed circle (ICseg) in this paper. The algorithm includes multi-step. It examines edges at first, and then produces a binary image with edges as foreground. After that, inscribed circles are created to cover the background of the binary image. In the first partition, the image is subdivided into separated regions by combining inscribed circles...
