Chinese word segmentation could be considered as a problem of word boundary recognition. Word boundary information plays a significant role in human language acquisition and automatic segmentation for Natural Language Processing (NLP). Extraction of word boundary information involves cognitive psychology, computational linguistics, and language education. Methods utilizing word boundary informa...

Automatic segmentation of the heart's left atrium offers great benefits for planning and outcome evaluation of atrial ablation procedures. However, the high anatomical variability of the left atrium presents significant challenges for atlas-guided segmentation. In this paper, we demonstrate an automatic method for left atrium segmentation using weighted voting label fusion and a variant of the ...

optical coherence tomography (oct) is a powerful imaging modality used to image various aspects of biological tissues, such as structural information, blood flow, elastic parameters, change of polarization states, and molecular content [1]. in contrast to oct technology development which has been a field of active research since 1991, oct image segmentation has only been more fully explored dur...

Lexical Cohesion is a commonly studied linguistic feature as it is easily identified from the surface of a text. However, the purposes for studying lexical cohesion are varied, and each purpose requires different methods. This study analyzes two short movie review texts for four different research purposes using lexical cohesion: text evaluation, text segmentation, text summarization, and text ...

We introduce a software system for semi-automatic segmentation of the patellar cartilage. By providing tools for sub-pixel accurate edge tracing, automatic contour completion, and adequate visualization we achieve a remarkable speed-up of the physician’s segmentation process. Our results show the exactness that can be reached for cartilage segmentation if expertise and automation are merged in ...

A robust method for plate segmentation in a License Plate Recognition (LPR) system is presented, designed to work in a wide range of acquisition conditions, including unrestricted scene environments, light, perspective and camera-to-car distance. Although this novel text-region segmentation technique has been applied to a very specific problem, it is extensible to more general contexts, like di...

This paper introduces a novel automatic video object extraction algorithm based on combination of color and motion segmentation results. The algorithm includes five parts: preprocessing, color segmentation, motion segmentation, combination of color and motion segmentation of multiple frames, post-processing. The performance of this algorithm is very promising, resulting in pixel-wise accuracy o...

We present a new method for delineating the osseous interface in ultrasound images. Automatic segmentation of the bone-soft tissues interface is achieved by mimicking the reasoning of the expert in charge of the manual segmentation. Information are modeled and fused by the use of fuzzy logic and the accurate delineation is then performed by using general a priori knowledge about osseous interfa...

Speech segmentations have been widely using in many speech applications. In speech synthesis, the quality of produced speech depends on the accuracy of labeled acoustic inventory. In speech recognition, segmented utterances according to the labels are usually used as a starting point for training speech models. The segmentation is often manually encoded which is timeconsumption process and has ...
