A novel camera calibration method for fish-eye lenses using line features
Photogrammetry Calibration Camera Geometric Close range Sensor
2014/9/9
In this paper, a novel method for the fish-eye lens calibration is presented. The method required only a 2D calibration plane containing straight lines i.e., checker board pattern without a priori kno...
Identification and classification of bulk paddy, brown, and white rice cultivars with colour features extraction using image analysis and neural network
stepdisc analysis HSI HSV back propagation algorithm, bulk images
2014/7/10
We identify five rice cultivars by mean of developing an image processing algorithm. After preprocessing operations, 36 colour features in RGB, HSI, HSV spaces were extracted from the images. These 36...
Scan registration using planar features
Registration Laser scanning Point cloud Segmentation
2014/7/30
Point cloud acquisition by using laser scanners provides an efficient way for 3D as-built modelling of indoor/outdoor urban environments. In the case of large structures, multiple scans may be require...
REMOTE SENSING IMAGE RETRIEVAL WITH COMBINED FEATURES OF SALIENT REGION
Visual Attention Model Object Saliency Salient Regions
2014/7/23
Low-level features tend to achieve unsatisfactory retrieval results in remote sensing image retrieval community because of the
existence of semantic gap. In order to improve retrieval precision, vi...
New radar images uncover remarkable features below the surface of the moon
New radar images uncover remarkable features belowthe surface of the moon
2014/6/12
New images of Earth’s Moon reveal more than can be seen with the naked eye, thanks to the combined efforts of the two largest radio telescopes of their kind -- the National Radio Astronomy Observatory...
An Investigation on the Effectiveness of Features for Translation Quality Estimation
Investigation Effectiveness Features Translation Quality Estimation
2014/3/20
We describe a systematic analysis on the effectiveness of features commonly exploited for the problem of predicting machine translation quality. Using a feature selection technique based on Gaussian P...
Existing state and features of relatively minor industrial accidents related to the use of roll box pallets (RBPs)
Existing state features relatively minor industrial accidents related roll box pallets
2013/9/30
Roll box pallets (RBPs) are four-wheeled cages that are used in many industries and contribute to efficient logistics services. However, we found that many work-related injuries to the hands and feet ...
