analytics: base class for analytics meta - GstAnalyticRelationMeta is a base class for analytics meta. It's able to store analytics results (GstAnalyticRelatableMtd) and describe the relation between each analysis results. - GstAnalysisRelationMeta also contain an algorithm able to explore analysis results relation using a bfs. - Relation(edge) between analysis results (vertice) are stored in an adjacency-matrix that allow to quickly identify if two analysis results are related and by which relation they related. It also work for indirect relation and can provide the path of analysis results by which two analysis results are related. - One allocation per buffer to store analysis results. Here we rely on the application to guess how much space will be required to store all analysis results. This is something that could be improved significantly but it's a starting point. - Define common analysis results, classification, object-detection, tracking that are subclass of GstAnalyticRelatableMtd. The also provide exemple of how to extend GstAnalyticRelatableMtd to have them benefit for the mechanim to express relation with other analysis results.

analytics: base class for analytics meta - GstAnalyticRelationMeta is a base class for analytics meta. It's able to store analytics results (GstAnalyticRelatableMtd) and describe the relation between each analysis results. - GstAnalysisRelationMeta also contain an algorithm able to explore analysis results relation using a bfs. - Relation(edge) between analysis results (vertice) are stored in an adjacency-matrix that allow to quickly identify if two analysis results are related and by which relation they related. It also work for indirect relation and can provide the path of analysis results by which two analysis results are related. - One allocation per buffer to store analysis results. Here we rely on the application to guess how much space will be required to store all analysis results. This is something that could be improved significantly but it's a starting point. - Define common analysis results, classification, object-detection, tracking that are subclass of GstAnalyticRelatableMtd. The also provide exemple of how to extend GstAnalyticRelatableMtd to have them benefit for the mechanim to express relation with other analysis results.

analytics: base class for analytics meta - GstAnalyticRelationMeta is a base class for analytics meta. It's able to store analytics results (GstAnalyticRelatableMtd) and describe the relation between each analysis results. - GstAnalysisRelationMeta also contain an algorithm able to explore analysis results relation using a bfs. - Relation(edge) between analysis results (vertice) are stored in an adjacency-matrix that allow to quickly identify if two analysis results are related and by which relation they related. It also work for indirect relation and can provide the path of analysis results by which two analysis results are related. - One allocation per buffer to store analysis results. Here we rely on the application to guess how much space will be required to store all analysis results. This is something that could be improved significantly but it's a starting point. - Define common analysis results, classification, object-detection, tracking that are subclass of GstAnalyticRelatableMtd. The also provide exemple of how to extend GstAnalyticRelatableMtd to have them benefit for the mechanim to express relation with other analysis results.

<record name="SegmentationMtd" c:type="GstAnalyticsSegmentationMtd" version="1.26">
<doc xml:space="preserve" filename="../subprojects/gst-plugins-bad/gst-libs/gst/analytics/gstanalyticssegmentationmtd.c">This type of metadata holds information on which pixels belongs to
a region of the image representing a type of object.
It supports two types of segmentation, semantic or instance:
* Semantic: All objects of the same type have the same id
* Instance: Each instance of an object has a different id
The results of the segmentation are stored in a #GstBuffer that has a
#GstVideoMeta associated with it. This buffer is stored in the
GstAnalyticsSegmentationMtd using
#gst_analytics_relation_meta_add_segmentation_mtd(). The #GstBuffer
containing the segmentation mask is image-like but the color values are
arbitrary values, referred by region-id in this API, without meaning beyond
specifying that two pixels in the original image with the same values in
their corresponding mask value belong to the same region.
To further describe a region, the #GstAnalyticsSegmentationMtd can be
associated with other #GstAnalyticsMtd. Since region ids are
generated by the segmentation process itself and are not always sequential,
we use a map of indexes to region ids starting with 0 without discontinuity
which facilitate N-to-N mapping with other #GstAnalyticsMtd. For
example it can be associated with #GstAnalyticsClsMtd to describe the class
of object matching the pixels of a segmented region.
Example: Associate Instance Segmentation with Classification
In the following example the segmentation process will fill segmask with
values of 0 for background, 12 for the first region which correspond to a
to a strawberry, 7 for the second region that also correspond to a
strawberry in the image and 31 for the third region that correspond to a
leaf in the image.

analytics: base class for analytics meta - GstAnalyticRelationMeta is a base class for analytics meta. It's able to store analytics results (GstAnalyticRelatableMtd) and describe the relation between each analysis results. - GstAnalysisRelationMeta also contain an algorithm able to explore analysis results relation using a bfs. - Relation(edge) between analysis results (vertice) are stored in an adjacency-matrix that allow to quickly identify if two analysis results are related and by which relation they related. It also work for indirect relation and can provide the path of analysis results by which two analysis results are related. - One allocation per buffer to store analysis results. Here we rely on the application to guess how much space will be required to store all analysis results. This is something that could be improved significantly but it's a starting point. - Define common analysis results, classification, object-detection, tracking that are subclass of GstAnalyticRelatableMtd. The also provide exemple of how to extend GstAnalyticRelatableMtd to have them benefit for the mechanim to express relation with other analysis results.
