Using an Extended Hough Transform Combined with a Kalman Filter to Segment Tubular Structures in 3D Medical Images
We present a new approach for the coarse segmentation of tubular structures in 3D image data. Our algorithm, which requires only few initial values and minimal user interaction, c...

Particle Filter with State Permutations for Solving Image Jigsaw Puzzles
We deal with an image jigsaw puzzle problem, which is defined as reconstructing an image from a set of square and non-overlapping image patches. It is known that a general instan...

Directional Filtering Transform for Image/Intra-Frame Compression
Abstract--While directional adaption is introduced into traditional transforms, different orders of two 1-D transforms will result in different results of one 2-D transform. Based ...

Accelerating 3D Convolution Using Graphics Hardware
Many volume filtering operations used for image enhancement, data processing or feature detection can be written in terms of threedimensional convolutions. It is not possible to y...
