COMPARISON OF UNSUPERVISED VEGETATION CLASSIFICATION METHODS FROM VHR IMAGES AFTER SHADOWS REMOVAL BY INNOVATIVE ALGORITHMS [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015
The recognition of vegetation by the analysis of very high resolution (VHR) aerial images provides meaningful information about environmental features; nevertheless, VHR images frequently contain shadows that generate significant problems for the ...

A $\left(k,n\right)$-Threshold Secret Image Sharing Scheme Based on a Non-Full Rank Linear Model

Mathematics, 2022
Secret image sharing is a hot issue in the research field of data hiding schemes for digital images. This paper proposes a general k,n threshold secret image sharing scheme, which distributes secret data into n meaningful image shadows based on a non ...

Beyond Shadowing: Providing Meaningful Clinical Experiences for Early Clinical Learners [PDF]

AEM Education and Training, 2017
Early in medical school, medical students traditionally received little instruction in patient care settings. The transition to clinical instruction was often abrupt. Kolb's model of experiential learning states that “learning is the process whereby knowledge is created through the transformation of experience.” 1 This belief that learning best occurs ...

Real-time, all-frequency shadows in dynamic scenes [PDF]

, 2008
Shadow computation in dynamic scenes under complex illumination is a challenging problem. Methods based on precomputation provide accurate, real-time solutions, but are hard to extend to dynamic scenes.

Smoke and Shadows: Rendering and Light Interaction of Smoke in Real-Time Rendered Virtual Environments [PDF]

, 2013
Realism in computer graphics depends upon digitally representing what we see in the world with careful attention to detail, which usually requires a high degree of complexity in modelling the scene.

Institutions and Shadows: Jonathan Swift, Enlightenment and Recent Irish Poetry [PDF]

Estudios Irlandeses, 2023
This article traces Jonathan Swift’s legacy in the work of three modern Irish poets: Jessica Traynor, Rita Ann Higgins and Derek Mahon. I use two motifs to explore this inheritance: institutions and shadows.
