Carbon fibres in carbon matrix composites, however, pose a difficult challenge to image analysis systems due to the poor contrast between the different phases.
Two big wave surfers from La Jolla, California, and Hawaii, Clinton Edwards and Clifford Kapono, are spear heading the challenge to image the world's best surf spots.
In computer vision, occlusions are almost always seen as undesirable singularities that pose difficult challenges to image motion analysis problems, such as optic flow computation, motion segmentation, disparity estimation, or egomotion estimation.
Following the second year, students were able to understand image acquisition limitations and methods to overcome challenges to image acquisition as well as utilize ultrasound during basic procedural guidance.
Vascular networks within a living organism are complex, multi-dimensional, and challenging to image capture.
In comparison to the human eye, the rodent eye has a large lens filling up most of the vitreous cavity, making it challenging to image the anterior segment.
Many mouse models of cancer develop metastasis in the lung, but this organ is particularly challenging to image for several reasons.
However, high-throughput, high-content image data sets are large both in total size and in terms of the total number of individual images, presenting significant challenges to image data management.
Note that it is significantly more challenging to image single molecules in live cells than in vitro because the signal-to-noise ratio (SNR) is much poorer - the molecules are not spatially fixed, the evanescent field is less uniform and there is an autofluorescence component to the signal.
It is challenging to image the human esophagus in vivo with balloon-based SECM, however, because patient motion and anatomic tissue surface irregularities decenter the optics, making it difficult to keep the focus at a predetermined location within the tissue as the beam is scanned.
But the civil liberties group's complaint to the Justice Department deals with the Booker era, a challenge to the image of a mayor who is often mentioned as a potential candidate for higher office.
