Social media is now playing a vital role in influencing people's sentiment in favor or against a government or an organization. Therefore, to understand the sentiment of any posting in social media, an efficient method is an ultimate necessity. We have analyzed some facebook postings to understand political sentiments. In any politically motivated posting there are some dominant keywords. At first,...
Noise can be easily induced in images during acquisition and transmission. Therefore, it is a basic requirement to remove noise from an image while keeping its features intact for better understanding and recognition. Gaussian and impulse are two very common types of noise. Tremendous research initiatives are being taken for removing these noises. Previously, we developed a fuzzy filter that effectively...
There is considerable literature indicating that class attendance is positively related to academic performance. However, the narrative on what influences students’ decisions to attend class is scant. This article examines why students choose not to attend class through the use of a survey distributed to first year undergraduates. Regression results point to three main reasons for reduced attendance...
Low density impulse noise can be successfully denoised by traditional median filter. But the performance badly deteriorates if the noise density is high. Recently fuzzy-based adaptive median filter has been introduced to handle high density noise in grayscale images. To make it more generalized in this paper we develop an adaptive fuzzy median filter to remove impulse noise from color images. Here...
Ultrasound imaging plays a crucial roles in medical field to estimate kidney size, position, appearance and helps to detect structural abnormalities as well as the presence of cysts, stones, cancer, congenital anomalies, swelling, blockage of urine flow etc. But presence of speckle noise and low contrast in ultrasound images, detection of kidney is a difficult as well as challenging task. In this...
Existing texts play an important role in understanding a scene image. Scene images differ from document images, which are composed of text characters of various size, shape, direction and situation along with complicated backgrounds, such as map, picture or painting, etc. Hence, the extraction of texts in scene images is a difficult as well as challenging task. Recently, mathematical morphology based...
