A model... videos from different sites. The results of the test confirm that the system is reliable and has an overall accuracy of over 85%.Key words:image processing technique; pedestrian detection; tracking......
dwell time (i.e., the coherent processing interval) into a focused two-dimensional image. However, actual targets observed by operational radar rarely have such an ideal motion. Targets are often engaged... the essential driving source of echo signal, thus generates higher resolution ISAR image [9-11]. After rang compression and envelope alignment, azimuth ISAR processing of echo signal is mainly based......
]. It is a new multi-resolution analysis framework and widely applied in various image processing problems. A curvelet transform involves four steps: 1) sub-band decomposition, 2) smooth partitioning, 3... that no other representation can yield a smaller asymptotic error with the same number of terms. Because of its surprising properties for image processing, a fast and accurate discrete curvelet transform......
