Due to obstruction by an object light from a source cannot reach the area and creates shadow on that area. Shadows often introduce errors in the performance of computer vision algorithms, such as object detection and tracking. Thus shadow detection and removal is a pre-processing task in these fields. This paper proposes a simple method to detect and remove(More)
DSJM is a software toolkit written in portable C++ that enables direct determination of sparse Jacobian matrices whose sparsity pattern is a priori known. Using the seed matrix S ∈ R n×p , the Jacobian A ∈ R m×n can be determined by solving AS = B, where B ∈ R m×p has been obtained via finite difference approximation or forward automatic differentiation.(More)
