Fruit detection in natural environment using partial shape matching and probabilistic Hough transform
TL;DR: Experiments demonstrated that the proposed approach was competitive for detecting most type of fruits, such as green, orange, circular and non-circular, in natural environments.

Multiscale Fourier descriptor based on triangular features for shape retrieval
Chengzhuan Yang,Qian Yu +1 more
TL;DR: This work introduces a novel multiscale Fourier descriptor based on triangular features which is used to identify shapes and is far superior to the complex shape description methods in terms of retrieval efficiency and computational complexity.

A Boundary-Fragment-Model for Object Detection
TL;DR: In this paper, a strong boundary fragment model (BFM) is proposed to detect object classes using only the object's boundary, which is able to detect objects principally defined by their shape rather than their appearance.

Photovoltaic panel extraction from very high-resolution aerial imagery using region–line primitive association analysis and template matching
TL;DR: This study combines OBIA and template matching techniques to address problems and aim for accurate photovoltaic panel (PVP) extraction from very high-resolution (VHR) aerial imagery and shows that the proposed method can successfully extract PVPs without any user-specified matching template or training sample.

Random sample consensus: a paradigm for model fitting with applications to image analysis and automated cartography
TL;DR: New results are derived on the minimum number of landmarks needed to obtain a solution, and algorithms are presented for computing these minimum-landmark solutions in closed form that provide the basis for an automatic system that can solve the Location Determination Problem under difficult viewing.

Normalized cuts and image segmentation
Jianbo Shi,Jitendra Malik +1 more
TL;DR: This work treats image segmentation as a graph partitioning problem and proposes a novel global criterion, the normalized cut, for segmenting the graph, which measures both the total dissimilarity between the different groups as well as the total similarity within the groups.

Shape matching and object recognition using shape contexts
TL;DR: This paper presents work on computing shape models that are computationally fast and invariant basic transformations like translation, scaling and rotation, and proposes shape detection using a feature called shape context, which is descriptive of the shape of the object.
