In this paper, a visual servo control approach, called "teach by zooming", is formulated where the objective is to position/orient a camera based on a reference image obtained by another camera.
We describe the design, realization and basic tests of a prototype Cone-Beam Breast Computed Tomography (CBBCT) scanner, combined with a SPECT head consisting of a compact pinhole gamma camera based on a photon counting CdTe hybrid pixel detector.
Some years ago, the authors have described an original scintillation gamma camera based on a matrix of 2×2 R5900-C8 Hamamatsu Position Sensitive PhotoMultiplier Tube (PSPMT) coupled to a scintillating array.
We propose a novel method for relighting the image of outdoor scenes viewed from a fixed camera based on a sparse set of images of the same scene under different illumination.
Traditionally, a visual servo control problem is formulated in the teach by showing framework with an objective to regulate a camera based on a reference (or desired) image obtained by a priori positioning the same camera at the desired task-space location.
Monocular navigation relies on finding an initial pose, i.e., a coarse estimate of the attitude and position of the space resident object with respect to the camera, based on a minimum number of features from a three dimensional computer model and a single two dimensional image.
We present the results of a comparative study between several scintillation sensors with the goal of optimizing the spatial resolution of a practical mini-gamma camera based on a 2×2 array of Hamamatsu H8500 flat panel position sensitive photomultiplier tubes (PSPMTs) with 64 anode pads per PSPMT.
In this paper, we propose a high-speed smart camera based on a CMOS sensor with embedded processing.
Partially slotted crystals have been designed and constructed and have been used to evaluate the performance with respect to the spatial resolution of a γ-camera based on a position-sensitive photomultiplier.
Executives of the company, Foveon, said they had given a prototype camera based on their chip to a photographer in Los Angeles, Greg Gorman, who had used it to make a portrait of a cowboy.
