The Solution
Solution
VidiCert enables significant automation of audiovisual content quality assessment
JOANNEUM RESEARCH’s VidiCert system automatically detects in video and moving image files a range of specific image and sound errors based on their subjective appearance. A user-interface optimised specifically for usage by QC operators, showing results of automatic detection intuitively and clearly in combination with the video essence, allows quick manual inspection and assessment. Compared to a fully manual quality inspection, VidiCert is able to reduce operator time drastically.
Technical Details
Significant automation of visual quality assessment
VidiCert is a software based solution enabling significant automation of audiovisual essence (baseband) quality assessment in a two-step approach. In the first step video or movie essence is analysed fully automatically in regard to audiovisual defects and properties, e. g. video breakup, block dropout, blurriness, noise or silence. In the second step, verification of the gathered information is done by a streamlined user interface enabling job-time optimisation. VidiCert offers efficiently the verification of the audiovisual technical quality as well as verification of the correct- and completeness of the video content. The result is a human verified quality report described in the standardised MPEG-7 format. So VidiCert is a “semi-automatic” video essence (baseband) QC system offering many visual and some audio checks. Verification by a human cannot be entirely avoided as human interpretation of results is required, but operator time is reduced to a minimum
