Feature transformation and key-point identifi is the solution to many local feature descriptors. One among such descriptor is the Scale Invariant Feature Transform (SIFT). A small effort has been made for designing a hexagonal sampled SIFT feature descriptor with its applicability in face recognition...

Aguado, in Feature Extraction and Image Processing for Computer Vision (Fourth Edition), 2020 7.3.2.4 Rotation and scale invariant moments Centralised moments are only translation invariant: they are constant only with change in position, and no other appearance transformation. In order to obtain ...
Focusing on applications to the three-dimensional (3D) garment computer aided design (CAD)system, a human features recognition method based on 3D scale invariant feature transformation (SIFT) is proposed in this paper. First of all, pre-processing is performed on the 3D scanned human body, ...
(SVM) classifier to detect vehicles within UAV imagery, achieving improved detection under diverse lighting conditions, albeit at a relatively slower inference speed. Moranduzzo et al.18utilized SVM to categorize the Scale-Invariant Feature Transform (SIFT) keypoints in UAV images into vehicle and ...
feature extraction techniques in the early stages heavily relied on manually crafted approaches such as scale-invariant feature transformation (SIFT)15and histogram of oriented gradients (HOG)16, which were tailored explicitly for distinct image feature types. The extracted features are subsequently utilize...
The invention discloses a depth image matching method based on ASIFT (Affine Scale-invariant Feature Transform). The method comprises the following steps: acquiring depth images and grayscale images of an object to be detected in two view fields, and respectively obtaining the corresponding ...
