This paper addresses the problem offreehand ultrasound probe tracking without requiring an external tracking device, by mounting a video camera on the probe to identify location relative to the patient's external anatomy. By pre-acquiring a high-resolution 3D surface map as an atlas ofthe anatomy, we eliminate the needfor artificial skin markers. We use an OpenDR pipeline for inverse rendering and...
We present a novel device mounted on the fingertip for acquiring and transmitting visual information through haptic channels. In contrast to previous systems in which the user interrogates an intermediate representation of visual information, such as a tactile display representing a camera generated image, our device uses a fingertip-mounted camera and haptic stimulator to allow the user to feel visual...
We present a novel and relatively simple method for clustering pixels into homogeneous patches using a directed graph of edges between neighboring pixels. For a 2D image, the mean and variance of image intensity is computed within a circular region centered at each pixel. Each pixel stores its circle's mean and variance, and forms the node in a graph, with possible edges to its 4 immediate neighbors...
