Digital Imaging: From Grains to Pixels

From Pixels to Buildings

This paper describes the land use classification of multispectral digital aerial images, the removal of buildings from the digital surface model and the visualization of the textured digital surface model with reconstructed buildings. The proposed approach applies spectral classification techniques to multispectral digital aerial images with RGB and NIR channels. The results of the land use cla...

From Letters to Pixels

Specifying regions of interest to search 3D anatomical space can be di cult. Ontology-based queries are often imprecise and return extra (unwanted) data. Drawing regions of interest in graphical 3D representations of a model organism in principle allows for high precision, but user interfaces can be awkward to use and time consuming. In this poster we promote the use of spatial descriptions as ...

Digital mammography: from planar imaging to tomosynthesis

Early investigations on the physical properties of digital mammography provided the impetus for further research [11-15]. These studies suggested that the image noise characteristics of digital systems could be better than for screenfi lm mammography. Therefore, the highresolution advantage of screen fi lm might not be as important for detection of microcalcifi cations in the breast as it was o...

Digital image compression: pixels n' bits.

From Pixels to Voxels: Tracking Volume Elements in Sequences of 3-d Digital Images

This paper presents the extension of certain, fundamental digital photogrammetric concepts, theories and strategies to three dimensions, and their performance in an interdisciplinary application for 3-D image sequence analysis in a technical chemistry experiment. Specifically, we present an image analysis technique for examining the fine scale (Kolmogorov scale) variations of the mixing process...
