Furse, Cynthia M. | Statistical comparison of capacity predictions for realistic MIMO channels | The impact of antenna polarization on channel capacity is explored in multiple-input, multiple-output (MIMO) systems. An idealized polarization model involving branch power rations (BPR's) and channel cross-coupling is incorporated into channel-specific capacity calculations. Results are compared f... | | 2007-01-01 |

Tasdizen, Tolga | Automatic markup of neural cell membranes using boosted decision stumps | To better understand the central nervous system, neurobiologists need to reconstruct the underlying neural circuitry from electron microscopy images. One of the necessary tasks is to segment the individual neurons. For this purpose, we propose a supervised learning approach to detect the cell membra... | | 2009 |

Mathews, V. John | Vector quantization of images using visual masking functions | ABSTRACT This paper presents an image compression technique that incorporates visual masking functions in vector quantizer systems. Visual masking functions provide a description of the maximum amount of noise that can be present in an image, while remaining undetected when the image is viewed by ... | | 1992 |

Harrison, Reid R. | Micropower circuits for bidirectional wireless telemetry in neural recording applications | State-of-the art neural recording systems require electronics allowing for transcutaneous, bidirectional data transfer. As these circuits will be implanted near the brain, they must be small and low power. We have developed micropower integrated circuits for recovering clock and data signals over ... | Micropower circuits; Neural recording systems; Low-power CMOS circuits, RF telemetry; Transcutaneous data link; Transmitter | 2005-01-01 |
