Sequential Extraction of Clusters by Fuzzy Hough Transforms.
The Journal of the Institute of Image Information and Television Engineers, 1997 ロバストなファジイクラスタリングの一方法としてファジィハフ変換に基づいてクラスタを逐次に抽出する方法を提案する.基本的な方針は可能性C平均法と同じくデータ分布のモードを抽出するものであり, このモード抽出にファジィハフ変換を用い, クラスタとして抽出されたデータを全体のデータから削除して順次クラスタを抽出していく.本方法の性質を簡単なデータで確認した後, 肌色領域抽出による顔検出の例に応用し, 本方法の有効性を確認する.

Sleep‐trackers in the wild: A faceted taxonomy for information and interaction design
Journal of the Association for Information Science and Technology, EarlyView.Abstract Consumer‐grade sleep‐tracking technologies (CSTs) have brought sleep into everyday data practices, reframing it from a clinical concern into a site of personal optimization and reflection. Yet existing taxonomies of sleep‐tracking often medicalize users and overlook the complexity of sleep‐tracking technologies. This paper presents SleepTax, a

Off-line Recognition of Unconstrained Handwritten Numerals Using Fuzzy Hough Transform
, 2009 A fuzzy system for handwritten numerals recognition using a fuzzy Hough transform technique is presented. The system is an off-line system since the data processed was written before the time of recognition.

History, EarlyView.Abstract This article offers new perspectives on the relationship between elementary teaching, scientific expertise and the professionalization of the human sciences. Previous scholarship has demonstrated the ready existence of ‘amateur’ science societies in the nineteenth century where cross‐class exchanges were common.

Journal of Microscopy, EarlyView.Abstract Transmission Kikuchi diffraction in the scanning electron microscope has gained popularity as a materials characterisation technique for its high throughput and nanometre‐level spatial resolution. While conventional diffraction pattern analysis routines focus on Kikuchi bands on the diffraction patterns, the full physical picture of electron ...
