We have developed a spatial light modulator technology based on foundry silicon fabrication processes. This technology employs a thin, ferroelectric liquid crystal light-modulating layer at the substrate's surface, producing electrically addressed display devices with resolutions up to 256x256 and frame rates up to 10 kHz. We have also fabricated optically addressed smart-pixel arrays for low-l...

This paper deals with the design of a micro-eyein-hand architecture. It consists of a smart camera embedded on a gripper. The camera is a high speed (10 000 fps) CMOS sensor of 64 × 64 pixels. Each pixel measures 35 μm × 35 μm and includes a photodiode, an amplifier, two storage capacitors, and an analog arithmetic unit. The gripper consists of a 4 dof (degrees-of-freedom) (y+, y-, z+, z-) micr...

The proposed research aims at inexpensive, specialized firmware solutions to smart algorithms designed to assist remote surveillance using a group of mini-UAVs. We identify an application problem, blind sources separation for sub-pixel target identification, that need to be resolved to compensate for either hardware inefficiencies or to reduce communication/energy consumption such that the depl...

The shortage of training samples remains one of the main obstacles in applying the artificial neural networks (ANN) to the hyperspectral images classification. To fuse the spatial and spectral information, pixel patches are often utilized to train a model, which may further aggregate this problem. In the existing works, an ANN model supervised by center-loss (ANNC) was introduced. Training mere...

Smart camera networks are very powerful for various computer vision applications. As a preliminary step in the application, every camera in the scene needs to be calibrated. For most of the calibration algorithms, image point correspondences are needed. Therefore, easy to detect objects can be used like LEDs. Unfortunately, existing LED based calibration methods are highly sensitive to lighting...

This paper describes the design, implementation and evaluation of a user-verification system for a smart gun, which is based on grip-pattern recognition. An existing pressure sensor consisting of an array of 44× 44 piezoresistive elements is used to measure the grip pattern. An interface has been developed to acquire pressure images from the sensor. The values of the pixels in the pressure-patt...

The smart pseudoscopic-to-orthoscopic conversion (SPOC) algorithm can synthesize a new elemental image array (EIA) using the already captured EIA, but only relies on one simulated ray to establish mapping relationship between display pixels and synthetic pixels. This paper improves SPOC proposes average algorithm, which fully considers converging effect of lens ray. In rays start from pixel, pa...
