An agricultural robot system and method of harvesting, pruning, culling, weeding, measuring and managing of agricultural crops. Uses autonomous and semi-autonomous robot(s) comprising machine-vision using cameras that identify and locate the fruit on each tree, points on a vine to prune, etc., or may be utilized in measuring agricultural parameters or aid in managing agricultural resources. The cameras may be coupled with an arm or other implement to allow views from inside the plant when performing the desired agricultural function. A robot moves through a field first to “map” the plant locations, number and size of fruit and approximate positions of fruit or map the cordons and canes of grape vines. Once the map is complete, a robot or server can create an action plan that a robot may implement. An action plan may comprise operations and data specifying the agricultural function to perform.

Graphics architectures, and methods that include use of representative Z values, are also disclosed.

Method, system, and article of manufacture for selecting prospects for a product promotion though data mining. An initial set of prospects in a customer database is identified, by data mining, as initially identified prospects based on predetermined selection criteria. The number of initially identified prospects is compared to a target number of prospects. When the number of initially identified prospects matches the target number of prospects, the initially identified prospects are utilized as the final selection of prospects. When the number of initially identified prospects mismatches the target number of prospects, the final selection of prospects is determined by performing a culling process or an augmenting process to reduce or increase, respectively, the initial set of prospects using a heuristic measure H, until the number of prospects in the initial set of prospects matches the target number of prospects.

Graphics processing devices and methods are provided for culling small primitives that do not cover any pixels. A boundary (e.g., a diamond) is defined around a pixel center, with pixel coverage being determined for some types of primitives based on whether the boundary is crossed. The boundaries divide the raster into internal regions and external regions. Each region is assigned a unique canonical identifier. Each vertex of a primitive is assigned the canonical identifier corresponding to the region that contains that vertex. The canonical coordinates of the vertices are used to cull primitives that do not satisfy the boundary crossing coverage rules for any pixels.

A method of efficiently removing backfacing primitives from the graphics pipeline such that rendering efficiency is increased. In one embodiment of the present invention, a bounding cone of normal vectors of a primitive is first determined during pre-processing. During the rendering process, before the primitive is drawn, the bounding cone is compared with a half-space defined by a viewing vector. Primitives whose bounding cones do not intersect with the half-space will be removed from further processing. In this way, rendering efficiency is increased. In another embodiment, a normal bit-vector is used to represent normal directions of a primitive, and a visibility bit-vector is used to represent visible normal directions. In that embodiment, primitives are culled efficiently by comparing the normal bit-vector with the visibility bit-vector.

Moreover, whether the drawn part is completely included in a known part of the cover mask is judged, and coordinated with a comparison of the draw minimum depth value and the dynamic maximum depth value, so as to determine whether to discard the drawn part and whether to update the cover mask and the dynamic maximum depth value in the Z cache memory. Accordingly, the bandwidth taken up in the system memory is reduced efficiently.

A concurrency-restricting lock may divide a set of threads waiting to acquire the lock into an active circulating set (ACS) that contends for the lock, and a passive set (PS) that awaits an opportunity to contend for the lock. The lock, which may include multiple constituent lock types, lists, or queues, may be unfair over the short term, but improve throughput of the underlying multithreaded application. Culling and long-term fairness policies may be applied to the lock to move excess threads from the ACS to the PS or promote threads from the PS to the ACS. These policies may constraint the size or distribution of threads in the ACS (which may be NUMA-aware). A waiting policy may avoid aggressive promotion from the PS to the ACS, and a short-term fairness policy may move a thread from the tail of a list or queue to its head.

According to embodiments of the invention, rays may be stochastically culled before they are issued into the three-dimensional scene. Stochastically culling rays may reduce the number of rays which need to be traced by the image processing system. Furthermore, by stochastically culling rays before they are issued into the three-dimensional scene, minor imperfections may be added to the final rendered image, thereby improving the realism of the rendered image. Therefore, stochastic culling of rays may improve the performance of the image processing system by reducing workload imposed on the image processing system and improving the realism of the images rendered by the image processing system. According to another embodiment of the invention, the realism of images rendered by the image processing system may also be improved by stochastically adding secondary rays after ray-primitive intersections have occurred.

Z-buffer rendering of three-dimensional scenes is made more efficient through a method for occlusion culling by which occluded geometry is removed prior to rasterization. The method uses hierarchical z-buffering to reduce the quantity of image and depth information that needs to be accessed. A separate culling stage in the graphics pipeline culls occluded geometry and passes visible geometry on to a rendering stage. The culling stage maintains its own z-pyramid in which z-values are stored at low precision (e.g., in 8 bits). The efficiency of hierarchical z-buffering is improved through hierarchical evaluation of line and plane equations.
