Traditionally the acquisition of real time panoramic images has been performed by the usage of lenses or mirrors coupled with standard image sensors, which give distorted images. In this paper we will present a system composed of a mirror and a log polar sensor, which is able to provide directly understandable images.

Abstract In this paper, we will propose a simple contact model of a soft fingertip based on geometrical analysis and statics of the fingertip. First, we introduce a virtual spring system to the soft fingertip corresponding to one and twodimensional contact between a planar object and a soft fingertip. Second, we describe pressure distribution, and estimate that equation by simulating and measur...

The need for technology to assist in medical monitoring applications is becoming more necessary in society as the number of patients in hospital and clinics continues to grow. The demand on staff to monitor every individual consistently becomes necessary. Wireless sensor networks (WSN) are now being used to facilitate this on-demand monitoring both at the patients home and in the hospital/clini...

The state of the art in machine vision inspection and a critical overview of real-world applications are presented in this paper. Two independent ways to classify applications are proposed, one according to the inspected features of the industrial product or process and the other according to the inspection independent characteristics of the inspected product or process. The most contemporary s...

An improved inertial and visual sensors calibration method is proposed in this paper, which is the method of fractional step to calibrate between inertial and visual sensors. The relationship of the rotation between inertial and vision sensors can be obtain by solving the improvement of hand-eye calibration equations. The inclinometer sensor is introduced in the process of calibration and the o...

A high speed VLSI image sensor including some preprocessing algorithms is described in this paper. The sensor implements some low-level image processing in a massively parallel strategy in each pixel of the sensor. Spatial gradients, various convolutions as Sobel or Laplacian operators are described and implemented on the circuit. Each pixel includes a photodiode, an amplifier, two storage capa...

With the development of satellite and remote sensing techniques, more and more image data from airborne/satellite sensors have become available. Multi-sensor image fusion seeks to combine information from different images to obtain more inferences than can be derived from a single sensor. In image-based application fields, image fusion has emerged as a promising research area since the end of t...

We report a novel event-driven correlated double sampling (CDS) technique for pulse-frequencymodulation (PFM) analog-to-digital converters (ADCs). PFM-ADCs are promising for pixel-parallel 3-D integrated image sensors with excellent imaging performance. The developed ADC with CDS consists of comparators, capacitors, and timing control logic circuits that are designed to generate the triggered c...

With the development of modern image sensors enabling flexible image acquisition, single shot high dynamic range (HDR) imaging is becoming increasingly popular. In this work, we capture single shot HDR images using an imaging sensor with spatially varying gain/ISO. This allows all incoming photons to be used in the imaging. Previous methods on single shot HDR capture use spatially varying neutr...

We describe discrim, a Matlab-based program for investigating image discriminability in various display systems. Discrim allows the user to manipulate images representing scene content. These images can be built up out of image primitives (sine wave gratings, Gabor patches) and image files from other sources. The user may then manipulate a model of the sensor and display characteristics. The se...
