In contrast to the mean-line based evaluation system, motif analysis and morphological filters are two techniques oriented to the characterization of functional properties of surfaces. The motif combination procedure is consistent with the functionality of the morphological closing filter that insignificant peaks on the profile are suppressed. By linking the functionality of the structuring ele...

In this paper, we describe a novel method for morphological façade analysis. The analysis consists of two parts: façade division and localization of windows. The façade division is based on the façade alignment hypothesis. We accumulate directional color gradients and we analyze the generated profile. Our approach introduces several morphological filters to augment the robustness to problems su...

Due to abundant spectral information contained in the hyperspectral images, they are suitable data for anomalous targets detection. The use of spatial features in addition to spectral ones can improve the anomaly detection performance. An anomaly detector, called nonparametric spectral-spatial detector (NSSD), is proposed in this work which utilizes the benefits of spatial features and local st...

A new segmentation method based on the morphological characteristic of connected components in images is proposed. Theoretical definitions of morphological leveling and morphological spectrum are used in the formal definition of a morphological characteristic. In multiscale segmentation, this characteristic is formalized through the derivative of the morphological profile. Multiscale segmentati...

Hyperspectral anomaly detection has attracted extensive interests for its wide use in military and civilian fields, three main categories of methods have been developed successively over past few decades, including statistical model-based, representation-based, deep-learning-based methods. Most these algorithms are essentially trying to construct proper background profiles, which describe the c...

Apeculiar lesion of superficial soft tissue characterised by fibroma-like morphology and an immunohistochemical profile consisting of CK+, VIM+, CD34+, CD31+/-, FLI1+ and INI-1 retained is described. The lesion entered into differential diagnosis with the so-called fibroma-like variant of epithelioid sarcoma, with the entities defined as ES-like/pseudomyogenic haemangioendothelioma and the rece...
