The generalization index system is one of the critical issues for computer-aided land use database generalization. This paper studies the scale and land use pattern effects on lan...
Abstract. A new simple and efficient database encryption scheme is presented. The new scheme enables encrypting the entire content of the database without changing its structure. I...
Advanced technology in GPS and sensors enables us to track physical events, such as human movements and facility usage. Periodicity analysis from the recorded data is an important...
We examine the problem of segmenting tracked feature point trajectories of multiple moving objects in an image sequence. Using the affine camera model, this motion segmentation pr...
Let be a finite, ordered alphabet, and consider a string x = x1x2 . . . xn n . A secondary index for x answers alphabet range queries of the form: Given a range [al, ar] , retu...
