KeyShip: Towards High-Precision Oriented SAR Ship Detection Using Key Points
Remote Sensing, 2023 Synthetic Aperture Radar (SAR) is an all-weather sensing technology that has proven its effectiveness for ship detection. However, detecting ships accurately with oriented bounding boxes (OBB) on SAR images is challenging due to arbitrary ship ...

Local Shape Descriptors for Neuron Segmentation [PDF]
Nature Methods, 2021 Abstract We present a simple, yet effective, auxiliary learning task for the problem of neuron segmentation in electron microscopy volumes. The auxiliary task consists of the prediction of Local Shape Descriptors ( LSDs ), which we combine with conventional voxel-wise direct ...

Chordiogram image descriptor based on visual attention model for image retrieval
Array, 2020 A novel shape-based image retrieval is presented in this study. The foreground and background contents of images are strongly concealed, so they are represented individually to reduce their influence on each other in the proposed approach.

Fruit shape classification based on wavelet descriptor
浙江大学学报. 农业与生命科学版, 2010 Shape is one of the most important features in fruit grading. A method for fruit shape classification based on the wavelet descriptor was proposed. Wavelet descriptor was extracted to describe the fruit shape from wavelet transform of the normalized ...

A Composite Descriptor for Shape Retrieval [PDF]
6th IEEE/ACIS International Conference on Computer and Information Science (ICIS 2007), 2007 In this paper, a composite descriptor for shape retrieval has been proposed. The proposed descriptor is obtained from generic fourier descriptors (GFD) for the shape region and the shape contour. A composite descriptor derived from GFD of the shape region and the shape contour is used for indexing and retrieval of shapes.

Fourier descriptors for broken shapes [PDF]
EURASIP Journal on Advances in Signal Processing, 2013 Fourier descriptors are powerful features for the recognition of two-dimensional connected shapes. In this article, we propose a method to define Fourier descriptors even for broken shapes, i.e. shapes that can have more than one contour. The method is based on the convex hull of the shape and the distance to the closest actual contour point along the ...
