Grayscale optical-flow methods have long been the focus of methods for recovering optical flow. Optical flow recovery from color-images can be implemented using direct methods, i.e. without using computationally costly iterations or search strategies. The quality of recovered optical flow can be assessed and tailored after processing, providing an effective, efficient tool for motion estimation...

in this paper, the mer-co(nh3)3(no2)3 complex was used as a new precursor for synthesizing spinel-type cobalt oxide nanoparticles (co3o4nps).thermal decomposition of the complex at low temperature (175 °c) resulted in the co3o4nps without using expensive and toxic solvents or complicated equipment. xrd, ft-ir, sem, edx, and tem were employed to characterize the product, and its optical and magn...

optical coherence tomography (oct) uses the spatial and temporal coherence properties of optical waves backscattered from a tissue sample to form an image. an inherent characteristic of coherent imaging is the presence of speckle noise. in this study we use a new ensemble framework which is a combination of several multi-layer perceptron (mlp) neural networks to denoise oct images. the noise is...

Compressive imagers acquire images, or other optical scene information, by a series of spatially filtered intensity measurements, where the total number of measurements required depends on the desired image quality. Compressive imaging (CI) offers a versatile approach to optical sensing which can improve size, weight, and performance (SWaP) for multispectral imaging or feature-based optical sen...
