Simulated annealing based optimization of dual-ring arrays for forward-looking IVUS and ICE imaging
(2010)
Forward-Looking (FL) catheter based imaging systems are highly desirable for guiding interventions in intravascular ultrasound (IVUS) and intracardiac echocardiography (ICE) applications. One of the main challenges in the ...
A novel image compression method based on classified energy and pattern blocks: initial results
(Springer, 2010)
In this work, a new method for the compression of the images based on the generation of the so called classified energy and pattern blocks is introduced and the initial results are presented. The initials results proved ...
A novel hybrid electrocardiogram signal compression algorithm with low bit-rate
(Springer, 2010)
In this paper, a novel hybrid Electrocardiogram (ECG) signal compression algorithm based on the generation process of the Variable-Length Classified Signature and Envelope Vector Sets (VL-CSEVS) is proposed. Assessment ...
Real-time frame buffer implementation based on external memory using FPGA
(Elsevier B.V., 2018)
