src_detection process user guide

Introduction

This modules describe the DoSrcDetectionProcess class used to implement the source detection process.

The tasks in the process are:

• DoImageProcessing, Image filtering by convolution
• DoSetBkgThreshTask, estimate of the bkg level and th. (DoSetBkgThresh)
• DoImageSegmentationTask, image segmentation (dbscan,NN,seg map) (DoImageSegmentation)
• DoSetDeblendingMethodTask, sets the deblending method
• DoDENCLUEDeblendingTask, denclue-based deblending (DoDENCLUEDeblending)
• DoGLWDeblendingTask, gauss-laplace watershed based deblending (DoGLWDeblending)
• DoSourceCatalogTask, catalog production, and source filtering
• DoDeblendingValidationTask validates the deblended products and produces the final list of detected source clusters (DoDeblendingValidation)

These tasks are orchestrated by the do_src_detection_process_func(), and the corresponding flow chart of the function is shown by the following diagram.

Class that implements the src detection process

do_src_detection_process_func(process, image)

This function implements the logic of the algorithm for the detection :class:DoSrcDetectionProcess.
