A frequent difficulty of image analysis is identification of false positive structures arising from background staining and tissue artefacts, thereby lowering the specificity and reliability of object recognition.
At the first evaluation, the students' inability to perform echocardiographic measurements because of the technical difficulty of image capture was 15.6% for the EF and CI, with great improvement throughout the training, as demonstrated by reductions in the inability rate to 6.3%and3.1%1%, respectively, in the second and the third stages of evaluation.
This may partly reflect the logistical difficulties of taking images underwater, but there is also a good chance that it may be due to a more widespread disconnection of humans with this type of environment.
Other outcomes included: immediate activation of other services; time needed for decision-making; technical difficulties; quality of images and diagnostic confidence (on a likert scale of 1 to 10).
First of all, it poses difficulties for image comparison itself by having to differentiate images of much similarity.
In situ quantification of the role of heterogeneities on fracture propagation is challenging because of the technical difficulty to image the interior of a 3D medium at high spatial resolution.
The evaluation was restricted to non-attenuation corrected images and reconstruction without collimator detector response compensations because of difficulties of generating DICOM images with the required header information for each gamma camera vendor.
"No," she says, citing the difficulty of finding images of mixed groups.
The HoGG method has achieved a good performance regardless of the difficulty of the images (occlusions, overlapping, carrying baggage, etc).
This could simply reflect that we were not at exactly the right durations to catch a dissociation due to variability in the experience of the participants, difficulty of the images and other cross-experiment differences between our study and those of Evans et al. (2013, 2016).
