Imaging sensor data modelling and evaluation based on optical composite characteristics: Investigation of data quality for inline inspection

Automated Fibre Placement is a common manufacturing technique for composite parts in the aero-space industry. Therefore, a visual part inspection is required which often covers up to 50% of the actual production time. Moreover, the inspection quality of this manual step fluctuates significantly. A camera-based automated inline inspection is...

Impact of Bit Errors in Digitized RF Data on Ultrasound Image Quality

This article quantitatively analyzes the impact of bit errors in digitized RF data on ultrasound image quality. The quality of B-mode images in both linear array and phased array imaging is evaluated by means of three objective image quality metrics: peak signal-to-noise ratio, structural similarity index, and contrast-to-noise ratio, when...

Visual Quality of Experience: A Metric-Driven Perspective

Multimedia systems are typically optimized in a way that maximizes users’ satisfaction of using the systems/services. This user satisfaction is what is commonly referred to as Quality of Experience (QoE). For visual media, such as images and videos, the optimization of QoE has meant reducing the visibility of artifacts (e.g. noise or other...

Semi-hidden target recognition in gated viewer images fused with traditional thermal IR images

Nowadays, for the defense and security community, it is of prior importance to classify threats that are merged in a background while at the same time understanding the context of the entire scene. Traditional TV and Infra-Red (IR) cameras allow for an easy context understanding by providing valuable background and scenery information....
