Analysis of Three-Dimensional Protein Images
Journal of Artificial Intelligence Research, 1997 A fundamental goal of research in molecular biology is to understand protein structure. Protein crystallography is currently the most successful method for determining the three-dimensional (3D) conformation of a protein, yet it remains labor intensive and relies on an expert's ability to derive and evaluate a protein scene model.

Contextual Visual Similarity [PDF]
arXiv, 2016 Measuring visual similarity is critical for image understanding. But what makes two images similar? Most existing work on visual similarity assumes that images are similar because they contain the same object instance or category. However, the reason why images are similar is much more complex. For example, from the perspective of category, a black dog

Conditional Diffusion on Web-Scale Image Pairs leads to Diverse Image Variations [PDF]
arXivGenerating image variations, where a model produces variations of an input image while preserving the semantic context has gained increasing attention. Current image variation techniques involve adapting a text-to-image model to reconstruct an input image conditioned on the same image.

Three-Dimensional Quantitative Cerenkov Luminescence Imaging [PDF]
, 2014 Cerenkov luminescence imaging (CLI) is an up-and-coming optical technique for in vivo imaging of beta-emitting radioisotopes. CLI relies on measurements of the Cerenkov radiation emitted when high-energy beta-particles travel through tissue.

Jpeg Image Compression Using Discrete Cosine Transform - A Survey [PDF]
arXiv, 2014 Due to the increasing requirements for transmission of images in computer, mobile environments, the research in the field of image compression has increased significantly. Image compression plays a crucial role in digital image processing, it is also very important for efficient transmission and storage of images. When we compute the number of bits per

Journal of Applied Clinical Medical Physics, EarlyView.ABSTRACT Background In radiotherapy for early‐stage glottic cancer, evaluating the target surface dose at the glottic air–tissue boundary is crucial, as buildup effect can cause underdosing. The accuracy of dose evaluation in the surrounding tissues is affected by both the dose calculation algorithms and the accuracy of the Hounsfield unit values in ...

Electron ptychographic microscopy for three-dimensional imaging
Nature Communications, 2017 Three-dimensional ptychographic imaging with electrons has remained a challenge because, unlike X-rays, electrons are easily scattered by atoms. Here, Gao et al. extend multi-slice methods to electrons in the multiple scattering regime, paving the way to
