“…It allows nine image scaling factors ranging from 1 × 1 to 2 × 2. Hutchison et al [22] present application of multimedia display processor which provides a cost effective and flexible platform for many video processing algorithms, including image scaling. In order to overcome the problems such as blurring and jagging around the edges, Liang et al [23] propose a coordinate rotation and kernel stretch strategy combined with the bilinear or bicubic algorithm.…”

This article proposes a real-time test and verification system for full-reference automatic image quality assessment and verification of digital TV sets. Digital camera is used for acquisition of the TV screen content in order to ensure quality assessment of the content as perceived by the user. Test has been executed in three steps: image acquisition by camera, TV screen content extraction and full-reference image quality assessment. The TV screen content is extracted from the captured image in two steps: detection of the TV screen edge and transformation of the TV screen content to dimensions of the reference image. Three image comparison methods are incorporated to perform full-reference image quality assessment. Reference image for quality assessment is obtained either by grabbing the image from TV set or by capturing the TV screen content on the golden sample. Digital camera was later replaced with DSP-based camera for image acquisition and algorithm execution which brought significant performance improvements. The comparison methods were tested under constant and variable illumination conditions. The proposed system is used to automate the verification step on the final production line of digital TV sets. The time required for verification step decreased by a factor of 5 when using the proposed system on the final production line instead of a manual one.

A built-in self-test technique that is applicable to symmetric microsystems is described. A combination of existing layout features and additional circuitry is used to make measurements from symmetrically located points. In addition to the normal sense output, self-test outputs are used to detect the presence of layout asymmetry that are caused by local, hard-to-detect defects. Simulation results for an accelerometer reveal that our self-test approach is able to distinguish misbehavior resulting from local defects and global manufacturing process variations. A mathematical model is developed to analyze the efficacy of the differential built-in self-test method in characterization of a wide range of local manufacturing variations affecting different regions of a device and/or wafer. Model predictions are validated by simulation. Specifically, it has been shown that by using a suitable modulation scheme, sensitivity to etch variation along a particular direction is improved by nearly 30%.[1394]
