Nowadays, the lung lobe segmentation is the most basic step in Lung CAD (Computer-aided diagnosis) and is playing an increasingly important role in the early diagnosis of lung diseases and the analysis of pulmonary functions. The key to achieving lung lobe segmentation is to detect and locate lung fissures. With the wide applications of HRCT (High-Resolution Computed Tomography), CT data with higher...
In this paper, we address the problem of detecting and localizing cars in still images. The proposed car detection system is based on a hierarchical feature detector in which the processing units are shunting inhibitory neurons. To reduce the training time and complexity of the network, the shunting inhibitory neurons in the first layer are implemented as directional nonlinear filters, whereas the...
Power-Law detector based on DFT is developed to detect a moving dim target under heavy infrared background. Because that the grey-scale value of a pixel in an image occurs fluctuation when a target passes by, this fluctuation can be viewed as a weak transient signal, and the Power-Law processor has advanced performance on transient signal detection. Firstly, a time window, length of L frames, is introduced...
