Breast cancer has increased decidedly among women. But with early diagnosis, a positive response to treatment can be given. Researchers are conducting various studies in imaging methods detect the disease and accurately. In this study, 9 cancerous images taken from TCİA image data bank were detected by K-mean clustering Otsu threshold method. Performance metrics evaluated comparing them marked ...

Due to the computational complexity of multilevel image thresholding, Swarm Intelligence Optimization Algorithm (SIOA) has been widely applied improve calculation efficiency. Therefore, more and attention paid exploring application latest SIOA in segmentation. This article takes Otsu fuzzy entropy as objective functions, using Coyote (COA) for thresholds optimization selection, through median a...

• TVJT: A puppet makes a statement about a story. A child’s task is to reward or correct the puppet based on the statement. • Previous studies: Children allow the long-distance zibun interpretation. Otsu (1990): disproportional salience of potential antecedents (zibun’s picture) Okabe (2008): failure to satisfy Condition of Plausible Dissent (Crain & Thornton 1998) Taro-wa Akira-ga zibun-ni pen...

Görüntü piksel değerlerini siyah-beyaz renge dönüştürülmesi eşikleme (thresholding), görüntü işleme yöntemiyle gerçekleştirilmektedir. Renkli bir griye dönüştürüldükten sonra görüntüye dönüştürülmektedir. Eşikleme sonunda görüntüler, en sade haline ulaşmaktadır. Eşik olarak kullanılacak değerin, doğru belirlenmesi gerekmektedir. Eğer eşik değeri, çok yüksek veya düşük olursa üzerinde kayıplar m...

Local high-order autocorrelation features proposed by Otsu have been successfully applied to face recognition and many other pattern recognition problems. These features are invariant under translation, but not invariant under scale and rotation. We construct scale and rotation invariant features from the local high-order autocorrelation features. x 1 Introduction In pattern recognition problem...

On 22 December 2018, volcano Anak Krakatau, located in Indonesia, erupted and experienced a major lateral collapse. The triggered tsunami killed at least 437 people by the 13-m-high tide. Traditional optical imagery plays great role monitoring volcanic activities, but it is susceptible to cloud fog interference has low temporal resolution. Synthetic aperture radar (SAR) can monitor activities h...

We present a comprehensive critical review of well-established satellite remote sensing water indices and offer novel, robust Augmented Normalized Difference Water Index (ANDWI). ANDWI employs an expanded set spectral bands, RGB, NIR, SWIR1-2, to maximize the contrast between non-water pixels. Further, we implement dynamic thresholding method, Otsu algorithm, enhance ANDWI's performance. Applie...
