Monitoring of rock fragmentation is a commercially important problem for the mining industry. Existing analysis methods either resort to physically sieving rock samples, or using image analysis software. The currently available software systems for this problem typically work with 2D images and often require a significant amount of time by skilled human operators, particularly to accurately delineate...
A compressive light field camera architecture has been proposed to recover light fields from a single image. This technique has recently gained increasing interest. The reconstruction quality of light field depends on the incoherence of a projection matrix and dictionary. Compressive light field acquisition is different from acquiring traditional signal while the projection matrix has specific structural...
Image segmentation seeks to partition the pixels in images into distinct regions to assist other image processing functions such as object recognition. Over the last few years dictionary learning methods have become very popular for image processing tasks such as denoising, and recently structured low rank dictionary learning has been shown to be capable of promising results for recognition tasks...
