The machine vision based inspection and measurement system obtains more significant advantages, such as higher speed and accuracy. A vision based embedded tiny spur gear inspection and measurement system is proposed. The system, which is designed for measuring gear's addendum and dedendum diameter, and inspecting the tooth deformation. In this system, Field-Programmable Gate Array (FPGA) is used to...
In this paper, a real-time vehicle detection system is designed and implemented on an FPGA (Field Programmable Gate Array). The system is composed of an infrared camera and an image acquisition and processing board developed by our research team. An FPGA chip and a DSP chip are embedded in the image board as the major calculation units, which make realtime computation possible. First, edge features...
Haustral folds are anatomically meaningful structures in the human colon. In this paper we present a method for haustral fold detection for CT colonography images. The 3D colon surface is first preprocessed into a 2D flattened colon. Then the image processing is done on 2D images. The proposed method makes used of a 2D Gabor filter to extract the feature of haustral folds. Then Sobel operator is performed...
