...It uses JIT compilation (via LLVM and its runtime TiRT) to offload compute-heavy code to CPUs, GPUs, mobile devices, and embedded systems. With built-in support for sparse data structures (SNode), automatic differentiation, AOT deployment, and compatibility with CUDA, Vulkan, Metal, and OpenGL ES, it empowers disciplines like simulation, graphics, AI, and robotics

...This is possible by exploiting the sparseness of the mathematical optimization problem. The original PTOptimizer uses the well proven Levenberg Marquardt optimizer lmdif from the minpack software. fastPTOptimizer uses a "sparse" optimizer lmdif_sparse that uses the SuiteSparse library.

The Objectron dataset is a collection of short, object-centric video clips, which are accompanied by AR session metadata that includes camera poses, sparse point-clouds and characterization of the planar surfaces in the surrounding environment. In each video, the camera moves around the object, capturing it from different angles. The data also contain manually annotated 3D bounding boxes for each object, which describe the object’s position, orientation, and dimensions. The dataset consists of 15K annotated video clips supplemented with over 4M annotated images in the following categories: bikes, books, bottles, cameras, cereal boxes, chairs, cups, laptops, and shoes. ...

...I found a way to normalize 1d wavefunction amplitude so this hack and its random heat vibrations are still unitary, even while microphone vibrating adds energy to part of 1d string of position and speed scalar arrays. The sparse part is, while the arrays are perfectly dense and linear, time is sparse when some springs vibrate with a larger multiplier of position subtracted from speed. In other words, this hack is a quanta level discontinuous field but in theory may be continuous as change in natural resonance frequency (what part of the "guitar string" would vibrate as if nothing acted on it) These few kilobytes of java code, many versions of CochleaSim.java and JSoundCard0.5 as an easily replaced dependency that reads microphone and writes to speakers as numbers ranging -1 to 1 44100 times per second, which is where SparseDoppler hooks in its array, microphone at one end and speakers hear the sum of the whole string.

cvsba is an OpenCV wrapper for the well-known Sparse Bundle Adjustment library (sba) by M. Lourakis. The main features are: - Based on sba-1.6, one of the most popular and robust bundle adjustment implementation, which is extensively used and tested by the community - sba installation is not needed since it is included in cvsba - New CMake structure which makes the library compilation, installation and linkage easier - Similar interface than Bundle Adjustment implementation on cv::LevMarqSparse::bundleAdjust() - Include examples to test the library on synthetically generated data - GPL licence
