Abstract

The present invention relates to an apparatus (100) and method for generating compression measurements of video using space-time integration. The device (100) comprises a detector (110) for detecting brightness values ​​of a temporal video structure over a time period from the optical data. The temporal video structure has pixels having horizontal and vertical dimensions with corresponding brightness values ​​over time periods. The device (100) also includes a space-time integrator unit (110) for receiving a plurality of measurement bases. And, a space-time integrator unit is used to apply each measurement basis to the temporal video structure, summarizing the corresponding values ​​of each measurement basis over a time period to obtain a measurement set. The aggregated value for each measurement base is the measurement set.

Description

Background technique [0001] Cameras or video cameras capture large amounts of data when acquiring image or video data. In order to store or transmit the captured data, the data is typically compressed after the video is captured. This compression typically utilizes a priori knowledge, eg N pixels can be approximated as a sparse linear combination of wavelength coefficients K smaller than N pixels. The wavelength factor can be calculated from the N pixel values ​​and stored or transmitted along with their positions. The standard procedure for transform coding of sparse signals is to take the entire N-sampled signal, compute the full set of transform coefficients, locate the K largest, significant coefficients and discard many small coefficients, and encode the value and location of the largest coefficients. This process is inefficient when N is large and K is small. However, acquiring large amounts of raw image or video data (large N) can be expensive where CMOS or CCD detec...
