Determining how Integrated circuits' (ICs) soft (transient) errors (also known as Single Event Upsets or SEUs) change with elevation is important in many applications, both on Earth and in aerospace. We have been studying SEUs using camera sensors, w

This paper presents the expansion of dark-frame non-uniformity correction (DFNUC) techniques to include compensation for thermal drift in a 128×128 PIN diode 3D flash LiDAR camera. Flash LiDAR cameras are operated in various climates, which makes th

In order to improve the imaging quality of large-scale infrared detectors, multiple parallel readout method of readout circuit was used in 160*120 uncooled pyroelectric IRFPA. Based on the uncooled pyroelectric IRFPA detector with multi channel outpu

In this paper, multi-dimensional extension and additional properties of already proposed extraction methods of buried one-dimensional signals in noise are developed. It is shown that heavy denoising uses no a-priori information, works without averagi

In uncooled long-wave infrared (LWIR) imaging systems, non-uniformity of the amplifier in readout circuit will generate significant noise in captured infrared images. This type of noise, if not eliminated, may manifest as vertical and horizontal stri

During formation of echocardiographic images, speckle noise is introduced, which diminishes important information present in an image and effects physician's capability to interpret image correctly. In the literature, many techniques have been propos

Image noise is one of the key issues in image processing applications today. The noise will affect the quality of the image and thus degrades the actual information of the image. Visual quality is the prerequisite for many imagery applications such a

Recently, image simulation has widely attracted people’s attentions. In this paper, we propose a novel statistical approach to remove salt-and-pepper noise. A statistic model of the number of noise pixels is built and the noise ratio of the corrupt

Impulse noise, also known as impulsive noise, is one of the most common types of noise occurring in digital images. The median filter and morphological filters are often used to remove impulsive noise, but these filters do not preserve image details.
