The paper presents the concept of a low-power, low-area, near-lossless image compressor for resource-constrained devices such as wireless capsule endoscopy (WCE). The compressor directly processes the raw data from the Bayer Color Filter Array (CFA)

The design, architecture and VLSI implementation of an image compression algorithm for high-frame rate, multi-view wireless endoscopy is presented. By operating directly on Bayer color filter array image the algorithm achieves both high overall energ

Discrete-time complex-valued analytic signal (AS) is widely used for instantaneous amplitude and phase demodulation of sinusoidal signals. Typically, AS is constructed with the use of Hilbert FIR filters designed by the window method or by some optim

Commercially available impedance meters can only measure at one frequency at the time. In this paper, we propose and validate multi-frequency impedance meter capable of simultaneous impedance measurement for several frequencies, which is very advanta

In this paper, the integer-to-integer Lifting Wavelet Transform (LWT) is investigated in application to compression of 8 channels neural data sampled at 20 kHz with 12-bit resolution. The LWT operates on integers, and all multiplications can be imple

Wireless data transmission accounts for a significant fraction of total power consumed by an implanted high-density microelectrode array neural recording system. It is well known that the problem can be mitigated by using an on-chip data compressor.

Wireless data transmission dominates the total power consumption of implanted multichannel neural recording system. However, it can be significantly reduced by using on-chip data compressor. It has been found that Discrete-time wavelet transform (DWT

The power consumption of implanted multichannel system is dominated by the wireless transmission and as such can be significantly reduced by using on-chip data compressor. This paper proposes a wavelet-based data compressor suitable for multichannel
