Finding best-fitted rectangle for regions using a bisection method

Global Contour and Region Based Shape Analysis and Similarity Measures

“…The first step is to detect the boundary of the object. The second step is to estimate its parameters based on the boundary points 2,7,8,77 . The parameters estimation procedures are discussed briefly.…”

“…Various properties of appearance such as texture, color and shape can be measured. Shape is a powerful tool for describing objects and differentiating between them, and has been extensively applied in many areas of computer vision 1,2 . In fact, the issue of shape extends far beyond computer vision into areas such as the graphic arts 3 , physics, chemistry and biology 4,5 .…”

“…Although the term similarity is often used, dissimilarity corresponds to the notion of distance: small distance means small dissimilarity, and large similarity. Shape similarity measures are used in building extraction and oil tank detection from remote sensing images 2,6,7,8 . Various shape features are often evaluated by how accurately they allow one to retrieve similar shapes from a designated database.…”

Minimum elastic bounding box algorithm for dimension detection of 3D objects: a case of airline baggage measurement

“…Thus, the survey of the measurement issue is expanded and summarised. For the methods in 2D space or 3D space, they can be divided into two categories roughly: geometric feature recognition methods [16][17][18][19][20] and shape approximation methods [21][22][23][24][25][26][27][28].…”

Forest Roadidentification and Extractionof Through Advanced Log Matching Techniques

“…(Shi and Zhu, 2002) Chaudhuri et al proposed a semi-automated road detection method with the directional morphological enhancement and segmentation. (Chaudhuri et al,2012) The existing methods were based on the facts that roads are linear features with edges and have different spectral signatures from surrounding objects. Such approaches may work well with major roads built with concrete or pavement, but fail to detect roads with vegetation coverage or under tree canopies shadows.…”
