Abstract

Color blindness is a condition in which a person can not distinguish certain wave light that can be distinguished by the normal eyes. Tests are currently being used (Ishihara Test and the Farnsworth Munsell) are simple. But, both of them have weakness in the form of test media used and requires appropriate room.       In this study, applies image processing to the development of color blindness level determination. Image processing is done by segmenting the pattern first with fuzzy color space segmentation. Having obtained the pattern of Ishihara image is used, then recombined with the initial image, so that the image obtained Ishihara with a segmented pattern. If the patient is able to see the pattern which is purposed, then continued to another image. However, if the patient can not see the pattern, then the pattern will be increased intensity of red, green and blue. By using a rule-based forward chaining, the determination of color blindness level is determined by the rules of the increase in the intensity of red, green and blue.          The research data is algorithm testing data which is created toward patients. Successful testing is done with total validation (normal patients and color deficiency) 97.8% and validation for diagnosted patients testing contained 85.7% of color deficiency. In the proposed algorithm is also used for the determination of the boundary wavelength capable of being viewed by people with color blindness.               Keywords: color blindness level, color segmentation, enhancements of color intensity

Abstract

Tuberculosis (TB) is an infectious disease caused by Mycobacterium tuberculosis. In this research, Ziehl-Neelsen sputum image is used to identify TB bacteria. Image segmentation process is done by using Otsu auto-thresholding to split object from its background in the ZN-stain sputum sample image. Morphology operation is done toward the splitting result to obtain the value of compactness, metric, and eccentricity of each object in the image which later will be used as input for the Adaptive Neuro-Fuzzy Inference System (ANFIS) to be classified. Result of the research show that segmentation using Otsu method is capable to properly split the object expected as bacteria from its background. The network testing show that ANFIS architecture with gbellmf as membership function type will work properly if it has 2 MFs on each input with epoch of 40.

Abstract

In this modern era, the identification system is becomes an important thing to be able to analyze a person based on the characteristics he has. In general, a person's identification system is still using conventional techniques, such as using ID cards that are easy to get off and lost passwords or PINs that are easily forgotten. In this research, the design of the system to identify or recognize a person using biometrics, especially the hand using Laplacian of Gaussian edge detection and Contour Extraction was carried out. The identification system with biometrics has many advantages because it is always attached to the body and can not be separated with humans. Stages performed in image processing in the form of RGB image conversion into binary using threshodling, edge detection using Laplacian of Gaussian as well as contour extraction using chain code representation. The result of contour extraction is the number of pixels calculated on each segment of the finger divided into 8 sections. The matching process on the system is done by using euclidean distance, ie calculate the smallest distance of similarity between the test image and the database. The result of identification conducted in this research using the feature extraction method, obtained accuracy of 93.33%.Keywords: Finger Biometrics, Laplacian of Gaussian Edge Detection, Contour Extraction
