Super-resolution (SR) is a technique that produces a high resolution (HR) image via employing a number of low resolution (LR) images from the same scene. One of the degradations that attenuates performance of the SR is the blurriness of the input LR images. In many previous works in the SR, the blurriness of the LR images is assumed to be due to the integral effect of the image sensor of the im...

Wireless Sensor networks are battery powered due to which their lifetime is very limited. In camera an equipped wireless sensor node, life time of sensor network is decreased quickly due to battery and processing power constraints when image is processed and is transferred to the destination. The image compression not only helps to reduce the communication latency but also gives energy efficien...

development of a suitable method for color sorting of agricultural products such as: tomato, apple and orange, based on surface reflection and image formation was the goal of this research. a suitable scheme of color differentiation using an optic head and electrical processing circuitry for separating red from green and other colors is presented. a photo-conductive transducer, electrical resis...

scanning hall probe microscopy (shpm) is a scanning probe microscopy technique developed to observe and image magnetic fields locally. this method is based on application of the hall effect, supplied by a micro hall probe attached to the end of cantilever as a sensor.  shpm provides direct quantitative information on the magnetic state of a material and can also image magnetic induction under a...

A concept for a novel CMOS image sensor suited for analog image pre-processing is presented in this paper. As an example, an image restoration algorithm for reducing image noise is applied as image pre-processing in the analog domain. To supply low-latency data input for analog image preprocessing, the proposed concept for a CMOS image sensor offers a new sensor signal acquisition method in 2D....

In the image sensors, the acquired image often differs from the real image in luminance or chrominance due to fabrication defects or nonlinear characteristics, which often lead to pixel defects or sensor failure. Therefore, the image acquisition characteristics of image sensors should be measured and tested before they are mounted on the target product. In this paper, the standardized test and ...

This study introduces an image sensor based visible light communication (VLC) and its application to pose, position, and range estimations. There are two types of visible-light receiver: a photodiode and an image sensor. A photodiode is usually used as a reception device of VLC, and an image sensor consisting of a large number of pixels can also be used as a VLC reception device. A photodiode d...

the research used the satellite image (landsat 7 etm ) within the thermal infrared sixth band (tir6) and geographic information system (gis) to determine the air pollution and its relationship with the land cover (lc) and land use (lu) of baghdad city. concentration of total suspended particles (tsp), lead (pb), carbon oxides (co, co2), and sulphur dioxide (so2) were obtained from 22 ground mea...

Complementary Metal Oxide Semiconductor (CMOS) image sensors have widely been used due to the advantages in terms of low power consumption, on-chip signal processing capability, and a comparatively low cost. The market research institutes predicted that the demand for CMOS image sensors will dramatically increase over the next few years. Although the demand continues to increase, the market is ...

Abstract The CMOS image sensor having VIPS(Vertically Integrated Photodiode Structure) was fabricated for the first time. By adding the high energy(~3MeV) ion implantation to the conventional CIS(CMOS Image Sensor) process, it was verified that the deep photo diode was successfully formed under the normal photodiode on a pixel. And it was observed that this image sensor can detect the visual im...
