On one hand,this paper compares the spatial analysis method in the landscape ecology with the latest histo-variogram method which was presented by Zhang Hao,et al in 2002 and then analyzes their advantages and shortcomings.

A new method for spatial matching of data with different resolution was proposed by introducing the concept of standing and contour pixels in histo-variogram theory, and was examined in quality validation using the sea surface temperature data obtained by FY2-C satellite.

According to the distinguishing feature of B scan ultrasonic image of liver,this paper puts forward the method of texture feature extraction with the use of the fractal feature together with sum and difference histograms.

Seeing that most of the traditional automatic video classification algorithms are complex and always waste lots of time,we proposed a simple video classification approach of histogram difference statistical method.
