Rice (Oryza sativa) breeders usually need to quantify the progress of their work by examining certain anatomical traits in the roots. These traits can be observed via a microscope. However, an efficient, accurate algorithm for image segmentation is required for quantitative analysis in a large dataset. This work proposes an automatic method based on graph optimization and multi-resolution analysis...
Independent Component Analysis (ICA) on a color model can be applied to measure heart rate without physical contact with subjects. Unfortunately, current non-contact systems need accuracy improvements to make them suitable for some medical applications. While others employed the most dominant frequency calculated by FFT as a heart rate, we propose to accumulate power spectrums across frequencies and...
Purpose Lung cancer remains the leading cause of cancer death in the United States. Central to the lung-cancer diagnosis and staging process is the assessment of the central-chest lymph nodes. This assessment requires two steps: (1) examination of the lymph-node stations and identification of diagnostically important nodes in a three-dimensional (3D) multidetector computed tomography (MDCT) chest...
