Both respiratory and cardiac motions reduce the quality and consistency of medical imaging specifically in nuclear medicine imaging. Motion artifacts can be eliminated by gating the image acquisition based on the respiratory phase and cardiac contrac

A cellular analog processor array for use in variable block-size motion estimation with a new simple method for shifting reference image data is presented. The new shift method leads to a greatly reduced number of neighborhood connections for each ce

HDR imaging is a technique that allows much larger range of luminosity to be expressed than the image sensor is able to capture. One way to acquire HDR images is to combine multiple low-dynamic-range images, taken with different exposure times, into

Online monitoring and closed-loop control of laser welding offer great possibilities for achieving better weld quality. Earlier work on visual laser welding monitoring has mainly focused on aluminum and fairly thin steel used, for example, in car pro

In micro energy harvesting applications one of the most essential blocks of the power management unit is the regulator. In this paper we present a low-power regulator consisting of a comparator, a voltage reference and an output voltage monitor. The

High-speed thermal imaging is necessary in many applications. However, the traditional column-wise readout implementations reduce the achievable frame rate. Also, analog integration for each individual pixel is not possible without sacrificing pixel

In this paper we present a new architecture for thermometer-coded digital-to-analog converters (DAC) that are used as a part of segmented DACs. The size of the binary-to-thermometer decoder tends to grow relatively large compared to the DAG when the
