The Ethiopian economy is based primarily on agriculture. Furthermore, due to Ethiopia's predominately agricultural economy, most Ethiopians are dependent agriculture in some way. In Ethiopia, traditional dishes including bread, injera, and soup commonly made from one of the plants, maize. Although growing maize, Wollo farmers experience low levels yield a variety problems. This study examines f...

Skin detection in images or videos plays a vital role in a wide range of image processing applications like face detection, face tracking, gesture analysis, human-computer interaction etc. Due to its high processing speed and invariant against rotation, it has received significant interest in pattern recognition and computer vision. The robustness of skin detection using color information depen...

This paper proposes a smartphone-based colorimetric pH detection method using a color adaptation algorithm for point-of-care applications. Although a smartphone camera can be utilized to measure the color information of colorimetric sensors, ambient light changes and unknown built-in automatic image correction operations make it difficult to obtain stable color information. This paper utilizes ...

automatic road extraction from aerial images can be very helpful in traffic control and vehicle guidance systems. most of the road detection approaches are based on image segmentation algorithms. color-based segmentation is very sensitive to light changes and consequently the change of weather condition affects the recognition rate of road detection systems. in order to reduce the light change ...

The authors report 4 experiments that examined color grouping and negative carryover effects in preview search via a probe detection task (J. J. Braithwaite, G. W. Humphreys, & J. Hodsoll, 2003). In Experiment 1, there was evidence of a negative color carryover from the preview to new items, using both search and probe detection measures. There was also a negative bias against probes on old ite...

One approach to change detection that is insensitive to illumination brightness and spectral changes uses properties of color imagery. This approach does not appear to have been previously investigated, and this paper asks: “What is the most appropriate metric for detecting changes in color imagery?”. We define and compare six image difference functions, mainly based on RGB and HSV image repres...

Reproducing skin colors pleasingly is essential for photographic color reproduction. Moving skin colors toward their preferred skin color center improves the skin color preference. Two main factors to successfully enhance skin colors are: a method to detect skin colors effectively and a method to morph skin colors toward a preferred skin color region properly. This paper starts with introducing...
