Abstract: Disclosed are an apparatus for configuring an equipment behavior catalog (EBC) and a virtual production system using an EBC. The apparatus for configuring the EBC according to an aspect of the present invention includes an artificial intelligence model storage configured to store an artificial intelligence model, and an EBC storage configured to store an EBC including artificial intelligence model data for the artificial intelligence model stored in the artificial intelligence model storage.

Abstract: In a target tracking method employing a block matching algorithm, pixels commonly included in target, background or foreground areas in consecutive frames are excluded from the calculation and only pixels in transition are taken into account. First, a first rectangular gate substantially including a target to be tracked is formed in an image of a first frame. Also, a second rectangular gate is formed in an image of a second frame temporally sequential to the first frame. Then, pixels commonly included in moving regions in the first and second rectangular gates are discriminated and a block matching level between the first and second rectangular gates is calculated by using only pixels of the moving region. Afterwards, the second rectangular gate is changed in a predetermined area, and the block matching level is calculated.

Abstract: A filtering method and a modified automatic regressive filter therefor are provided. The modified automatic regressive filter includes: a frame memory for storing one frame of the output of the filter; a frame difference generating portion for receiving the signal stored in the frame memory and an observed signal, to output a frame difference, and determining whether the current pixel belongs to a non-moving region or a moving region to output a moving index; a histogram generator for converting the frame difference of the non-moving region into a cumulative distribution function required for calculating the variance of noise in the non-moving region of the observed signal; and a selective filter output portion for selectively outputting the observed signal unaltered in the moving region and the signal passed via an adaptive filter having the gain calculated based on the output data of the histogram generator in the nonmoving region.
