A method and system is provided for the compression of a video captured from a static camera. A background image and an original image is captured from the static camera. A foreground object is extracted by taking the difference between the transformed original image and the transformed background image. The foreground object is represented as a sparse vector using wavelets. The method revolves around the compressive sensing framework by ingeniously using the complex field BCH codes and the syndrome as measurements to achieve robust background subtraction using reduced number of measurements. The reconstruction is carried out by a Complex-field BCH decoder coupled with block based implementation. According to another embodiment, an adaptive techniques has also been proposed for acquiring the measurements required for recovering the images.


This disclosure relates generally to ge visual inspection systems, and more particularly to a method and system for facilitating real time detection of linear infrastructural objects in aerial imagery. In one embodiment, a background suppression technique is applied to one or more hardware processors to a HSV image. Further, a mean shift filtering technique is applied to the hardware processors to find a peak of a confidence map and then a gradient image generation is performed for a plurality of edges of the image. A seed point pair along a middle cut portion of a linear feature of the HSV image to identify one or more boundaries of the seed point pair is extracted and then a contour growing approach to detect the boundaries of the linear feature is initiated. Lastly, one or more false positives are removed by using a rigidity feature, the rigidity feature being equivalent to the total sum of gradient orientations.


The present invention relates to a reusable physical financial instrument and a system and a method for enabling the financial instrument to perform multiple financial transactions. The financial instrument is capable of creating mixed reality experience when it comes in vicinity of the payor or payee device or ATM. Through the created mixed reality experience, the payor and the payee inputs payor-side and payee-side transaction and biometric data which are stored onto smart chip of the instrument and/or on Cloud Storage using cloud computing interface. The stored payor-side and payee-side transaction data are cross-validated and their biometric data is further verified against golden copy at the respective financial institutions or at the Central Authoritys repositories for performing the financial transaction. Upon completing the transaction, the payor-side and the payee-side data is erased, deleted or invalidated from the smart chip, thus making the financial instrument reusable for performing another transaction.
