Hough Transform-Based Angular Features for Learning-Free Handwritten Keyword Spotting.

Handwritten keyword spotting (KWS) is of great interest to the document image research community. In this work, we propose a learning-free keyword spotting method following query by example (QBE) setting for handwritten documents. It consists of four key processes: pre-processing, vertical zone division, feature extraction, and feature matching.

The efficacy of pulsed radiofrequency treatment of cervical radicular pain patients.

Objective: Cervical radicular pain is defined as pain arising in the arm caused by irritation of a cervical spinal nerve or its roots. Although many treatment modalities are described in the literature, the available evidence for efficacy is not sufficient to allow definitive conclusions. The goal of this study was to establish the benefits and prognostic factors of pulsed radiofrequency (PRF) on the adjacent cervical dorsal root ganglia (DRG) of cervical radicular pain patients.
