In the context of ChiVO (www.chivo.cl) used for search of ALMA data, processing tools and image analysis to detect and classify astronomical structures are developed.
We will show an algorithm to identify and classify astronomical structures at different scales using the wavelet transform (WT) in 2D images. WT provides a matrix to decompose it into several images of different scales. Identifying objects in WT is, given a scale, isolate structures.
Then a classification algorithm is applied to recognize the structures and incorporate them into an astronomical catalog.
