A digital image is a finite set of integer lattice points in an ambient Euclidean space together with suitable adjacency relation between points. Subdivision, which process enlarging the photographic sense, provides basic tool for operating images. But given map images, there as yet no general way to define their subdivisions that might reasonably be called subdivision map. In this paper, we co...
We define a fundamental group for digital images. Namely, we construct functor from images to groups, which closely resembles the ordinary algebraic topology. Our construction differs in several basic ways previously established versions of setting. development gives prominent role subdivision show that our is preserved by subdivision.
OBJECTIVE Sub-standard quality in X-ray image acquisition and interpretation is common in low-resource countries, and can ultimately result in higher patient morbidity and mortality. This study aimed at evaluating; 1) feasibility of implementing a digital X-ray device in a second level hospital in Angola; 2) quality of digital X-ray images, when digital radiology was in the hands of local techn...
