Feynman Liang created SPARK-8490: ------------------------------------ Summary: SURF Feature Transformer Key: SPARK-8490 URL: https://issues.apache.org/jira/browse/SPARK-8490 Project: Spark Issue Type: Sub-task Components: ML Reporter: Feynman Liang
Speeded up robust features (SURF) (Bay et al, ECCV 2006, http://www.vision.ee.ethz.ch/~surf/eccv06.pdf) is an image descriptor transform very similar to SIFT (SPARK-8486) but can be computed more efficiently. One key difference is using box filters (Difference of Boxes) to approximate the Laplacian of the Gaussian. We can implement SURF in Spark ML pipelines as a org.apache.spark.ml.Transformer. Given an image Array[Array[Numeric]], the SIFT transformer should output an ArrayArray[[Numeric]] of the SURF features for the provided image. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
