> This filter is not finished yet. Currently, for visual effect, it
> detects objections and draws a box for the detected objections with score >
> The purpose here is to show the previous changes of the dnn is necessary,
> and it is also a RFC (require for comment) patch for this filter.
> In my plan, an example under doc/examples will be added to show how to
> use this filter and connet the filter result with the ROI encoding.
> And, will add options to this filter for score_threshold, visual effect or not.
> And, a new type of sidedata will be added to hold the filter result.
> So, the example can get the filter result and set ROI info for encoder.
> Looks that, it is not easy to transfer data between filters, between
> filter and application, between filter and encoders, the current feasible
> method I found is to by sidedata.
