From the 90's, the image information retrieval methods have been on progress. As good examples of the methods, Conventional histogram method and merged-color histogram method were introduced. They could get good result in image retrieval. However, Conventional histogram method has disadvantages if the histogram is shifted as a result of intensity change. Merged-color histogram, also, causes mor...

An algorithm is designed for the histogram representation of an image, subsequent detection of Salt and Pepper (SP) noise in the image and finally the restoration of the image from this noise. The image is first represented as histogram, then fuzzy rule are applied on this. The images taken up for experimental analyses are subjected to the fuzzy based filter for SP noise removal. The proposed a...

Chein-I Chang, MEMBER SPIE University of Maryland Baltimore County Department of Computer Science and Electrical Engineering Baltimore, Maryland 21228-5398 E-mail: [email protected] Abstract. Entropic thresholding provides an alternative view to the design rationale of conventional thresholding. Abutaleb proposed a second-order entropic thresholding approach to improve Pun’s first-order ent...

A new psychophysical methodology is introduced, histogram contrast analysis, that allows one to measure stimulus transformations, f, used by the visual system to draw distinctions between different image regions. The method involves the discrimination of images constructed by selecting texture micropatterns randomly and independently (across locations) on the basis of a given micropattern histo...

As we know, histogram matching is a commonly-adopted technique in the applications of pattern recognition. The matching of two patterns can be accomplished by matching their corresponding histograms. In general, the number of features and the resolution of each feature will determine the size of histogram. The more the number of features and the higher the resolution of each feature, the strong...

Purpose: To evaluate the ability of ADC based histogram parameters to differentiate between benign and malignant gynecologic lesions. Results: The study was performed on 100 cases having 66 lesions &34 which were pathologically proved. There statistically significant difference qualitative diffusion weighted. range traditional partial slice mean parameter for masses (1.095 ± 0.315 x 10−3 mm...

In this letter, we propose a new histogram equalization method to compensate for acoustic mismatches mainly caused by corruption of additive noise and channel distortion in speech recognition. The proposed method employs an improved test cumulative distribution function (CDF) by more accurately smoothing the conventional order statisticsbased test CDF with the use of window functions for robust...

purpose : to assess the results of 1-minute and 5-minute schirmer's test (st) when the eyes are open (sto) and closed (stc) in normal participants. methods : in a comparative, observational case series study, 34 normal volunteers were included in the study. inclusion criteria were normal ophthalmologic findings except for refractive errors, no use of contact lenses, no history of previous ...
