The greenhouse environment monitoring requires high accuracy of data, and there are many redundancies and errors in the data collected through the wireless sensor network. In order to improve the accuracy of data, the paper proposes a method which is applying the kalman filtering algorithm to the data fusion and introducing the improved distribution map method to improve kalman filtering algorithm...
The stack phenomenon existed in milk somatic cell pictures and the shape irregularity. In this paper, firstly a suitable shape factor selected judges whether it occurred in touching. This is in order to reduce false segmentation. An improvement watershed method is proposed which is mainly used in resolving the over-segmentation problem. The idea is obtaining the central points in the local maximum...
The selection of color space is one of the determinants of the image segmentation quality, the segmentation results will be more accurate if the appropriate color space is adopted. In this paper, five kinds of color space RGB, HSI, YIQ, YCbCr, Lab are compared by three types of evaluation methods. The third method of image segmentation quality evaluation is proposed in this paper. The results shows...
In view of the shape irregularity and the stack phenomenon in milk somatic cell pictures. An improvement watershed method is proposed in the paper, which is mainly used in resolving the over-segmentation problem in watershed algorithm. Its main idea is: distance transformation is used for binary image firstly, obtaining the central points in the local maximum regions (seed points), and merging the...
