Using interframe correlation in a low-latency and lightweight video codec

The resolution of our screens never ceases to increase which means that the data rate of the videostreams increases as well. This becomes a problem for use-cases were uncompressed videostream is used, the bandwidth of some physical links is too limited to allow an uncompressed videostream with those new resolutions. Traditional compression like HEVC can not be used because it is too complex and its latency is too important. This is why lightweight and low-latency compression was created; it allows to compress the videostream in a visually lossless way and its low latency and complexity make it a perfect solution to replace uncompressed videostream. Up until now, most of those low-latency codec do not use interframe correlation to compress the information as it is considered an expensive feature. However, this master thesis explores the way to use interprediction with the constraints of low latency and low complexity in the software implementation of an existing codec: TICO. The new codec created is called ITICO and the results of this software implementation will allow intoPIX S.A. to decide in which use-cases the features are worth implementing in hardware.
