The purpose of this study was to determine the effectiveness electrocoagulation method in reducing turbidity, color concentration and COD levels on Jumputan wastewater treatment. electrodes used are aluminum plates as anode cathode. variations research were speed agitation system (batch intermittent system). fixed variable is a voltage 3.5 volts, 2 aluminium electrodes, 250 ml volume wastewater...

When two differently colored, superimposed patterns of dots rotate in opposite directions, this yields the percept of two superimposed transparent surfaces. If observers are cued to attend to one set of dots, they are impaired in making judgments about the other set. Since the two sets of dots are overlapping, the cueing effect cannot be explained by spatial attention. This has led to the inter...

This study analyzed the luminance and color emmetropization response in chicks treated with the nonselective parasympathetic antagonist atropine and the sympathetic β-receptor blocker timolol. Chicks were binocularly exposed (8h/day) for 4days to one of three illumination conditions: 2Hz sinusoidal luminance flicker, 2Hz sinusoidal blue/yellow color flicker, or steady light (mean 680lux). Atrop...

In order to solve the conflict between the size constraints of mobile phone cameras and image quality, it is an effective approach to improve the light sensitivity of imaging sensors. A color filter array comprising sparsely distributed crosses of color sampling blocks is proposed, in which nearly 69% of elements are transparent ones that detect luminance directly with a higher sensitivity than...

The color reduction in digital images is an active research area in digital image processing. In many applications such as image segmentation, analysis, compression and transmission, it is preferable to have images with a limited number of colors. In this paper, a color clustering technique which is a combination of a Kohonen Self Organized Featured Map (KSOFM) and a fuzzy clustering algorithm ...

Color is the most important properties for object discrimination. It is an object component that adds a new dimension to the machine vision. The color images on low devices are displayed having limited number of colors called as color palette reduction to cut down the storage requirements. In this paper we investigate the problem of averaging aggregation functions to select the appropriate func...

'Color from motion' describes the perception of a spread of subjective color over achromatic regions seen as moving. The effect is produced with a stimulus display consisting of colored dots, randomly placed upon a white field, with dots in the test region differing in both chromaticity and luminance from those in the surround. Evidence is presented suggesting that color from motion may be regu...
