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

In this paper, we propose an effective object detection framework based on proposal fusion of multiple sensors such as infrared camera, RGB cameras, radar and LiDAR. Our framework first applies the Selective Search (SS) method on RGB image data to ex

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

We describe a novel data-processing and analysis pipeline for optical observations of moving objects, either of natural (asteroids, meteors) or artificial origin (satellites, space debris). The monitoring of the space object populations requires reli

Robust real-time object detection and tracking are challenging problems in autonomous transportation systems due to operation of algorithms in inherently uncertain and dynamic environments and rapid movement of objects. Therefore, tracking and detect

We present design principles for implementing decoders for low-density parity check codes in CMOL-type memristive circuits. The programmable nonvolatile connectivity enabled by the nanowire arrays in such circuits is used to map the parity check matr

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