Organ-specific autoimmune diseases such as oophoritis, gastritis, thyroiditis, and orchitis were induced in female or male nude (nu/nu) mice by the transfer of nu/+spleen cells from which particular Lyt T cell subset(s) had been removed: treated with anti-Lyt-1 plus complement (C) caused disease recipient mice; anti-Lyt-2 C-treated spleen cells, contrast, did not. The responsible for induction are believed to be Thy-1+, Lyt-1-, 2,3- (Thy-1, Lyt-1, 2,3), since mixed antisera, including...

We have obtained viable and functional populations of antigen-binding cells enriched up to 500-fold from primed spleen-cell suspensions by fluorescent labeling a new electronic cell sorter that sorts according fluorescence. Concomitantly, largely depleted were obtained. While neither population alone is capable full adoptive secondary response when injected into irradiated recipients, reconstituted mixture restores the unfractionated spleen cells. Admixture sources unprimed thymus-derived...

Registration and integration of measured data real objects are becoming important in 3D modeling for computer graphics computer-aided design. We propose a new algorithm registration multiple range images producing geometric object surface model. The determines set rigid motion parameters that register image to given mesh-based is an the iterative closest point with least median squares estimator. After registration, points input classified into inliers outliers according errors between each...

Growth monitoring is an essential task in agriculture for obtaining good crops and sustainable management of cultivation. Though it essential, also a hard requiring much labor working time, many automation approaches have been proposed. We present attempt to estimate the leaf area tomatoes grown sunlight-type plant factory. scanned tomato plants by RGB-D sensor that moves vertically scan one side from pathway. built point cloud merging data, we segmented into four classes (Stem, Leaf, Fruit,...

This research develops a robotic vision and manipulation technologies for random bin-picking. Especially, we focus on the technology where dual-arm manipulator first picks up an object from pile, then regrasps it right hand to left hand, finally places fixture. We explain overview of our project. Then, about grasp/manipulation planner manipulator. Here, grasp is well applied objects which can be approximated by multiple cylinders. Also, pick-and-place effectively find regrasping posture...

We propose a method to construct 3-D geometric shape model by registering and integrating multiple range images under unified framework. use points around the object surface as correspondence key, because closest data point from an arbitrary should be matched if are registered correctly with some exceptional cases. assume that input shapes roughly in advance, then we solve problem iterative loops consist of establishing searching points, integration corresponded registration each integrated...

Registration and segmentation of multiple range images are one the most important problems in image analysis. This problem has been investigated by a number researchers, but existing methods easily affected outlying points (outliers) like noise occlusion. We first propose robust method estimating rigid motion parameters from pair images. is an integration iterative closest point (ICP) algorithm with random sampling least median squares (LMS) estimator. then detect outliers thresholding...

Abstract Reconstructing 3D shapes from images are becoming popular, but such methods usually estimate relative depth maps with ambiguous scales. A method for reconstructing a scale‐preserving shape monocular endoscope image sequences through training an absolute prediction network is proposed. First, dataset of synchronized RGB and created using simulator. Then, supervised trained that estimates map minimizing the loss compared to ground‐truth map. The predicted sequence aligned reconstruct...

Modelling object shapes from multiple range images requires three procedures: removal of measurement errors, registering input and integrating them as a shape representation. We propose unified framework in which these procedures can be solved simultaneously. Discrete samples the signed distance field (SDF) surface are used If data registered correctly, SDF should match common coordinate system. The first integrated by averaging assuming that they roughly pre-registered. to matching SDF....

We propose a method of filling unmeasured regions shape models integrated from multiple measurements surface shapes. use the signed distance field (SDF) as representation that contains information normal along with at closest point on sampling point. solve this problem by iteratively fitting quadratic function to generate smoothly connected SDF. analyzed relationship between coefficients and curvature, using coefficients, we evenly propagated SDF so it satisfies constraints field. The...

We describe a novel method, which extends the search algorithm of k-d tree for aligning and merging range images. If nearest neighbor point is far from query, many leaf nodes must be examined during search, actually will not finish in logarithmic time. However, such distant as important applications, images; reason this either because it consequently used or its weight becomes very small. Thus, we propose new that does strictly by pruning branches if lies beyond certain threshold. call...

Conventional registration algorithms are mostly concerned with rigid-body transformation parameters between a pair of 3D range images. Our proposed framework aims to determine, in unified manner, not only such rigid but also various deformation parameters, assuming that the we handle here is strictly defined by some parameterized formulation derived from mechanism. While conventional usually calculate six (three translation and three rotation parameters), our algorithm estimates as well. In...

We propose a method of computing surface curvature properties from the signed distance field (SDF) samples in 3D space. The SDF representation contains information normal at closest point on sampling point. variance these different points within neighborhood reflects information. Because this is done space, we do not directly referees to parametric coordinates or polygon structures. computation stable because it requires only linear algebraic operations. It possible extract multiple scale...

A feasible framework automatic object categorization is proposed based comparison, where distinguishing regions are simultaneously detected as well. High coincidence between our result and previous archaeological speculations observed validation experiments, which confirms the validity method.
