In recent times, there has been a huge increase in the average number of cases skin cancer per year, which sometimes become life threatening for humans. Early detection various diseases through automated techniques plays crucial role. However, presence numerous artefacts makes this task challenging. Dermoscopic images exhibit variations, including hair artefacts, markers, and ill-defined bounda...

In an effort to implement fast and effective tank segmentation from infrared images in complex background, the threshold of the maximum between-class variance method (i.e., the Otsu method) is analyzed and the working mechanism of the Otsu method is discussed. Subsequently, a fast and effective method for tank segmentation from infrared images in complex background is proposed based on the Otsu...

Digital image segmentation based on Otsu’s method is one of the most widely used technique for threshold selection. With Otsu’s method, an optimum threshold is found by maximizing the between-class variance and the algorithm assumes that the image contains two classes of pixels or bi-modal histogram (e.g., foreground and background). It then calculates the optimal threshold value separating the...

Diabetic Retinopathy is a effect of diabetes. It results abnormalities in the retinal blood vessels. The can cause blurry vision and blindness. Automatic vessels segmentation on image detect these vessels, actually resulting faster more accurate results. paper proposed an automatic vessel method that combined Otsu Thresholding with enhancement techniques. In enhancement, it CLAHE Top-hat transf...

Banjir merupakan salah satu bencana alam yang sering terjadi di Indonesia setiap tahunnya, sehingga menimbulkan berbagai permasalahan akibat adanya banjir. Hujan dengan intensitas tinggi kerap Kota Bogor. Dengan kondisi topografi berada pada kemiringan lereng relatif landai dan terletak dataran rendah, pertengahan bulan Oktober 2022 hujan ini, menyebabkan genangan banjir sejumlah wilayah Dalam ...

Multilevel thresholding image segmentation is one of the most widely used methods in field segmentation. This paper proposes a multilevel technique based on an improved whale optimization algorithm. The WOA has been applied to many complex problems because its excellent performance; however, it easily falls into local optimization. Therefore, firstly, mixed-strategy-based algorithm (MSWOA) prop...

purpose : to offer a semi-automatic algorithm to determine the area of angiographic hyperfluorescence methods : the proposed algorithm included wavelet filter, histogram equalization and modified otsu thresholding. hyperfluorescent area of 30 angiographic images obtained from patients with leaking choroidal neovascularization (cnv) and diabetic retinopathy were evaluated and the results were co...
