DIGITAL-BORN ILLUSTRATION TECHNIQUE: LOW POLY

An Illustration Technique for Unstructured D Meshes

Geometric relations in an irregular D polyhedron or tetrahedral mesh are often di cult to comprehend even for relatively few vertices A technique for illustrating such meshes which aids this comprehension is described in terms of several independent components i e edge representation viewpoint and perspective projection and light ing These images are suitable for embedding in dynamic displays o...

A Novel Low-shock Calibration Method Using Digital Filter Technique

− A piezoelectric accelerometer output voltage with zero shift was induced by the low-frequency response of the charge amplifier. So we designed a virtual amplifier with same input-output characteristic as the charge amplifier, and shock sensitivities of a piezoelectric accelerometer were evaluated by applying the input acceleration to the virtual amplifier. The shock sensitivities were compara...

Born Digital: Understanding the First Generation of Digital Natives

A Low Power Digital Accumulation Technique for Digital-Domain CMOS TDI Image Sensor

In this paper, an accumulation technique suitable for digital domain CMOS time delay integration (TDI) image sensors is proposed to reduce power consumption without degrading the rate of imaging. In terms of the slight variations of quantization codes among different pixel exposures towards the same object, the pixel array is divided into two groups: one is for coarse quantization of high bits ...

Illustration watermarking: an object-based approach for digital images

For most applications common watermarking techniques usually spread the data to embed over the entire media, since distributing the watermark information promises an improvement in regard to security aspects, data hiding capacity or rather robustness in terms of redundancy. Distribution is controlled by a a visual or psychoacoustical model that takes limitations of the Human Visual System (HVS)...
