It is believed that the excessive multifarious preventing measures are useless in tunnel. In this paper, depending on the analyses on the fire classification of tunnel the development law of different fire airflow, some correlative preventing measures are proposed by the requirements of currently road tunnel. They includes the requirements of aeration wind speed, the setting of vent of smoke, the...
The Probabilistic Index Map (PIM) model was originally proposed for video processing to extract background of video frames. In this paper, we introduce the PIM model for texture segmentation. We first extract texture features based on Laws and Gabor filters respectively. Then we present a fuzzy k-means method to generate the index map and palette, and use the PIM model to improve the segmentation...
This work compares supervised and unsupervised techniques to classify images of boar sperm heads according to their membrane integrity. We have used 5 different descriptors to characterize the texture of the acrosomes: Laws method, Legendre moments, Zernike moments and 4 and 13 of the features proposed by Haralick extracted from the co-occurrence matrix. We have carried out the classification using...
