WhatsApp is a software application that allows the exchange of text messages, videos, audios, images and photo between mobile phone users. The multi-modality function represents an interesting mode casual conversation can be examined simultaneously from sociological linguistic point view. This study discourse lexical analysis conversations two distinct groups. Aspects studied with sociolinguist...

diagnosis of corneal diseases is possible by measuring and evaluation of corneal thickness in different layers. thus, the need for precise segmentation of corneal layer boundaries is inevitable. obviously, manual segmentation is time‑consuming and imprecise. in this paper, the gaussian mixture model (gmm) is used for automatic segmentation of three clinically important corneal boundaries on opt...

This paper presents a new automatic image enhancement method by modifying the gamma value of its individual pixels. Most of existing gamma correction methods apply a uniform gamma value across the image. Considering the fact that gamma variation for a single image is actually nonlinear, the proposed method locally estimates the gamma values in an image using support vector machine. First, a dat...

content-based image retrieval and text-based image retrieval are two fundamental approaches in the field of image retrieval. the challenges related to each of these approaches, guide the researchers to use combining approaches and semi-automatic retrieval using the user interaction in the retrieval cycle. hence, in this paper, an image retrieval system is introduced that provided two kind of qu...

Image co-segmentation is important for its advantage of alleviating the ill-pose nature image segmentation through exploring correlation between related images. Many automatic algorithms have been developed in last decade, which are investigated comprehensively this paper. We firstly analyze visual/semantic cues guiding co-segmentation, including object and cues. Then, we describe traditional m...
