Counting jelly beans: voxel carving and segmentation of a container of heterogenous objects
In this report, we discuss our implementation of an ensemble of computer vision methods that serve to help provide an estimate of the number of jellybeans in a glass jar, a well-known parlor game. To do this, we decompose our methods into two spheres: 1. volumetric stereo voxel carving of the jar’s convex hull (to estimate the total volume), and 2. segmentation algorithms to count the number of...
متن کاملVideo Carving
We present a technique for summarizing a video into a short segment, while preserving the important events in the original. While many techniques remove whole frames from the video stream when condensing it, we observe that these deleted frames need not come from a single time step. More generally, deleted frames are “sheets” through the space-time volume. This leads to an algorithm whereby she...
متن کاملShadow Carving
The shape of an object may be estimated by observing the shadows on its surface. We present a method that is robust with respect to a conservative classification of shadow regions. Assuming that a conservative estimate of the object shape is available, we analyze images of the object illuminated with known point light sources taken from known camera locations. We adjust our surface estimate usi...
متن کاملArc Carving
In this paper we present a new technique for improving the azimuth resolution of ultrasonic range sensors frequently used with mobile robots. This improvement is achieved without a significant increase in the latency, or processing delay, of the system. Our approach decreases the azimuth uncertainty of a sensor reading by eliminating portions of the reading that are contradicted by subsequent r...
متن کاملForensic Data Carving
File or data carving is a term used in the field of Cyber forensics. Cyber forensics is the process of acquisition, authentication, analysis and documentation of evidence extracted from and/or contained in a computer system, computer network and digital media. Extracting data (file) out of undifferentiated blocks (raw data) is called as carving. Identifying and recovering files based on analysi...
