Global Thresholding and Multiple-Pass Parsing

by Joshua Goodman , 1997
"... We present a variation on classic beam thresholding techniques that is up to an order of magnitude faster than the traditional method, at the same performance level. We also present a new thresholding technique, global thresholding, which, combined with the new beam thresholding, gives an addi ..."

A fast iterative shrinkage-thresholding algorithm with application to . . .

by Amir Beck, Marc Teboulle , 2009
"... We consider the class of Iterative Shrinkage-Thresholding Algorithms (ISTA) for solving linear inverse problems arising in signal/image processing. This class of methods is attractive due to its simplicity, however, they are also known to converge quite slowly. In this paper we present a Fast Iterat ..."

Iterative Shrinkage-Thresholding Algorithm (FISTA) which preserves the computational simplicity of ISTA, but with a global rate of convergence which is proven to be significantly better, both theoretically and practically. Initial promising numerical results for wavelet-based image deblurring demonstrate

Extending RD-OPT with Global Thresholding for JPEG Optimization

by Viresh Ratnakar, Miron Livny - Proceedings of Data Compression Conference , 1996
"... In this paper, the RD-OPT algorithm for optimizing Discrete Cosine Transform quantization tables [RL95] is extended to incorporate global thresholding. Performance gains are possible by zeroing off some DCT coefficients in DCTbased image compression. We describe a global thresholding scheme, in whic ..."

Random Early Detection Gateways for Congestion Avoidance.

by Sally Floyd , Van Jacobson - IEEELACM Transactions on Networking, , 1993
"... Abstract-This paper presents Random Early Detection (RED) gateways for congestion avoidance in packet-switched networks. The gateway detects incipient congestion by computing the average queue size. The gateway could notify connections of congestion either by dropping packets arriving at the gatewa ..."

at the gateway or by setting a bit in packet headers. When the average queue size exceeds a preset threshold, the gateway drops or marks each arriving packet with a certain probability, where the exact probability is a function of the average queue size. RED gateways keep the average queue size low while

White Blood Cell Segmentation and Counting Using Global Threshold

by Prof J. B. Nemane, Prof V. A. Chakkarwar, Prof P. B. Lahoti
"... Abstract--Blood helps our body fight off infectious agents and inactivates toxins, stops bleeding through its clotting ability, and regulates our body temperature. Doctors rely on many blood tests to diagnose and monitor diseases the idea of our paper is to serve the pathologists, medical technician ..."

Then an automatic and efficient system is necessary and helpful In this paper Image Arithmetic and Global Threshold Method WBC nucleus segmentation that can be used to separate the nucleus

Cleaning of Ancient Document Images Using Modified Iterative Global Threshold

by N. Venkata Rao, A. V. Srinivasa Rao, S. Balaji, L. Pratap Reddy
"... Ancient document Image processing is an important area attracting many researchers in the recent period. Binarization is the first step while cleaning the document for further processing. Based on the degradation of the original document, either global or local thresholding methods are preferred. Th ..."

A NOVEL GLOBAL THRESHOLD-BASED ACTIVE CONTOUR MODEL

by Nuseiba M. Altarawneh, Brian Regan
"... In this paper, we propose a novel global threshold-based active contour model which employs a new edge-stopping function that controls the direction of the evolution and stops the evolving contour at weak or blurred edges. The model is implemented using selective binary and Gaussian filtering regula ..."

Govindaraju ”Separating Text and Background in Degraded Document Images - A Comparison of Global Thresholding Techniques for Multi-Stage Thresholding

by Graham Leedham, Saket Varma, Anish Patankar, Venu Govindaraju - Proceedings Eighth InternationalWorkshop on Frontiers of Handwriting Recognition,September
"... Before any processing of the textual content of a document image can be performed the text must be separated from the background of the image. Several thresholding algorithms have previously been proposed and are widely used in document processing. None have been shown effective at thresholding diff ..."

In this paper we investigate the use of three global thresholding algorithms (Otsu’s, Kapur’s entropy and Solihin’s quadratic integral ratio (QIR)) as the first stage in a multi-stage thresholding algorithm for use in degraded document
