Grey-level hit-or-miss transforms—part II: Application to angiographic image processing

Grey-level hit-or-miss transforms - part II: Application to angiographic image processing

The hit-or-miss transform (HMT) is a fundamental operation on binary images, widely used since 40 years. As it is not increasing, its extension to grey-level images is not straightforward, and very few authors have considered it. Moreover, despite its potential usefulness, very few applications of the grey-level HMT have been proposed until now. Part I of this paper [B. Naegel, N. Passat, C. Ro...

Grey-level hit-or-miss transforms - Part I: Unified theory

The hit-or-miss transform (HMT) is a fundamental operation on binary images, widely used since 40 years. As it is not increasing, its extension to grey-level images is not straightforward, and very few authors have considered it. Moreover, despite its potential usefulness, very few applications of the grey-level HMT have been proposed until now. Part I of this paper, developed hereafter, is dev...

The TARGET trial: hit or miss?

Over the past 8 years large-scale, placebo-controlled trials have established the efficacy of intravenous platelet glycoprotein (GP) IIb/IIIa inhibitors at reducing the 30-day composite of death, myocardial infarction, and urgent target vessel revascularization associated with percutaneous coronary angioplasty, atherectomy, and stent placement. Using abciximab, tirofiban, or eptifibatide, each ...

Generalized Hit - Miss Operators with Applications to Document Image Analysis

The morphological operators of a hit-miss transformation, opening, and closing are generalized in a number of ways. The new operators are useful for solving a variety of binary image analysis problems that involve pattern detection and reconstruction. Generalized openings are developed by replacing erosions with hit-miss operators. These new openings are shown to be anti-extensive, idempotent, ...
