چکیده
t—This paper describes a new method for the segmentation and extraction of cardiac MRI s. Our method is based on the novel use of a 2D bank. By convolving the tagged input image with ilters, the tagging lines are automatically enhanced ted out. We design the Gabor filter bank based on age’s spatial and frequency characteristics. The is a combination of each filter’s response in the bank. We demonstrate that compared to bandpass ds such as HARP, this method results in robust and mentation of the tagging lines.

Abstract This paper presents a robust watermarking for still digital images based on schur factorization and Singular Value Decomposition (SVD). In this paper, image is decomposed into 8 8 blocks and after applying schur factorization, the stable largest eigen values of the upper triangle is used as robust locations for embedding watermark. The matrix array formed by largest eigen values furt...

The assumption that cerebrospinal fluid (CSF) inflow and outflow is an essential element of an intracranial compartment (IC) model has been recently questioned [3]. The idea proposed in [3] that the free displacement of the CSF is one of the significant sources of the brain compliance is supported in this paper by computing an overall system compliance with a novel algorithm. The compliance obt...

Phase resetting of cells in response to a brief current pulse has been observed in a variety of nervous tissues including cardiac cells. External stimulation of the sinoatrial node is due to largely positive currents, depolarising the cells, except for some ACh interactions. Factors influencing this include the timing of the current injection, its polarity, magnitude and duration. Both prolonga...
