A highly accurate and robust deep checkerboard corner detector
Electronics Letters, 2021 Checkerboard corners are routinely used during tasks such as camera calibration, and accurate detection of them is essential. Traditional methods such as those based on the Harris corner detector are usually affected by image artefacts such as noise and ...

Evaluation of Stereo Images Matching [PDF]
E3S Web of Conferences, 2021 Image matching and finding correspondence between a stereo image pair is an essential task in digital photogrammetry and computer vision. Stereo images represent the same scene from two different perspectives, and therefore they typically contain a high ...

Independent Motion Detection with Event-driven Cameras [PDF]
, 2017 Unlike standard cameras that send intensity images at a constant frame rate, event-driven cameras asynchronously report pixel-level brightness changes, offering low latency and high temporal resolution (both in the order of micro-seconds).

Weed Density Detection Method Based on Absolute Feature Corner Points in Field
Agronomy, 2020 Field weeds identification is challenging for precision spraying, i.e., the automation identification of the weeds from the crops. For rapidly obtaining weed distribution in field, this study developed a weed density detection method based on absolute ...

Incremental refinement of image salient-point detection [PDF]
, 2008 Low-level image analysis systems typically detect "points of interest", i.e., areas of natural images that contain corners or edges. Most of the robust and computationally efficient detectors proposed for this task use the autocorrelation matrix of the ...

A Modified Harris Corner Detection for Breast IR Image [PDF]
Mathematical Problems in Engineering, 2014 Harris corner detectors, which depend on strong invariance and a local autocorrelation function, display poor detection performance for infrared (IR) images with low contrast and nonobvious edges. In addition, feature points detected by Harris corner detectors are clustered due to the numerous nonlocal maxima.

Multi-Threshold Corner Detection and Region Matching Algorithm Based on Texture Classification
IEEE Access, 2019 In order to address the unreasonable distributed corners in single threshold Harris detection and expensive computation cost incurred from image region matching performed by normalized cross correlation (NCC) algorithm, multi-threshold corner detection ...
