Image-based Modeling Using a Two-step Camera Calibration Method
We present a two-step camera calibration process based on linear least squares formulations. We show how to apply this process to build an integrated modeling environment, in which a scene is modeled by having the user specify, on a given image, a set of reference points (used for camera calibration) and object points (used for positioning the objects in the scene). Once this has been done, syn...
متن کاملUsing complicated, wide dynamic range driving to develop models of single neurons in single recording sessions.
Neuron models are typically built by measuring individually, for each membrane conductance, its parameters (e.g., half-maximal voltages) and maximal conductance value (g(max)). However, neurons have extended morphologies with nonuniform conductance distributions, whereas models generally contain at most a few compartments. Both the original conductance measurements and the models therefore unav...
متن کاملPerceptual Dynamic Range for In-Camera Image Processing
Image sensors in digital cameras capture values which are proportional to light intensity and within a range of between 3-4 orders of magnitude. These values are typically passed through a non-linearity prior to quantisation to a range of around 2 orders of magnitude. The purpose of the non-linearity is to ensure that the quantisation rate is approximately proportional to human sensitivity (see...
متن کاملHigh Dynamic Range Image Capture with Plenoptic 2.0 Camera
We demonstrate high dynamic range (HDR) imaging with the Plenoptic 2.0 camera. Multiple exposure capture is achieved with a single shot using microimages created by microlens array that has an interleaved set of different apertures. © 2009 Optical Society of America OCIS codes: (040.1490) Cameras, 110.5200 Photography.
متن کاملNon-Linearity in Wide Dynamic Range CMOS Image Sensors Utilizing a Partial Charge Transfer Technique
The partial charge transfer technique can expand the dynamic range of a CMOS image sensor by synthesizing two types of signal, namely the long and short accumulation time signals. However the short accumulation time signal obtained from partial transfer operation suffers of non-linearity with respect to the incident light. In this paper, an analysis of the non-linearity in partial charge transf...
