In a computer-aided system for skin cancer diagnosis, hair removal is one of the main challenges to face before applying process automatic lesion segmentation and classification. this paper, we propose straightforward method detect remove from dermoscopic images. Preliminarily, regions consider as candidate border/corner components located on image frame are automatically detected. Then, determ...

Noise removal or noise suppression is an important task in image processing. In general, the results of the noise removal have a strong influence on the quality of the following image processing techniques. Several techniques for noise removal are well established in gray value image processing. However, it is not easy to adapt these techniques to color image processing. The median filter is of...

Pseudomonas otitidis WL-13, which has a high capacity to decolorize triphenylmethane dyes, was isolated from activated sludge obtained from a wastewater treatment plant of a dyeing industry. This strain exhibited a remarkable color-removal capability when tested against several triphenylmethane dyes under both shaking and static conditions at high concentrations of dyes. More than 95% of Malach...

The Freundlich model was evaluated for use to assess the effect of heat on the adsorption capacity of an activated carbon for decolorizing/deodorizing corn zein. Because zein protein and its color/odor components are all adsorbed by activated carbon, a method to monitor their removal was needed. Yellow color is due to xanthophylls; a contributor to off-odor is diferuloylputrescine. The off-odor...

The treatment of paper mill effluent for COD, TOC, total phenols and color removal was investigated using combined activated sludge-ozonation processes and single processes. The combined activated sludge-O3/pH 10 treatment was able to remove around 80% of COD, TOC and color from Kraft E(1) effluent. For the total phenols, the efficiency removal was around 70%. The ozonation post treatment carri...

Colonoscopy video frames might be contaminated by bright spots with unsaturated values known as specular reflection. Detection and removal of such reflections could enhance the quality of colonoscopy images and facilitate diagnosis procedure. In this paper we propose a novel two-phase method for this purpose, consisting of detection and removal phases. In the detection phase, we employ both HSV...

ozonation was carried out for decolorization and coD removal of raw and anaerobically treated uAsb (upflow anaerobic sludge blanket) combined industrial (mainly textile) effluent in a lab-scale bubble column reactor. ozonation of anaerobic bioprocess effluent at a dose of 300 mg/h for 10 min resulted in 81% color and 75% coD removal (100 mgo3/80 mg coD) while for raw wastewater 25 min ozonation...

background: application of potassium ferrate is a chemical oxidation approach used for water and wastewater treatment. the aim of this study is to apply central composite design (ccd) and response surface methodology (rsm) to optimize potassium ferrate consumption in the treatment of wastewater from carpet industries. methods: samples in this experimental study were collected from wastewater, o...
