Again, Big Thank You for new Histogram Matching tool. I have first tried it with single band set, and am now playing with RGB composite images. Works nicely. When I fed SAGA with RGB composite, the tool splitted it into the bands and I could choose one from them. It's great, I don't have to split bands beforehand.

Wow, Thanks Volker! Thanks Olaf! ﾍ(^o^ﾍ)(/^o^)/ﾍ(^o^ﾍ)(/^o^)/

Dear SAGA users, In short my question is "Is it possible to make histogram matching between two images, using SAGA?" Not sure if this makes sense, but please consider I am trying to compare NDVI of two old Landsat images without metafiles (taken in the same year) . What I have in my mind is WhiteBox GAT's Histogram matching (two images) tool. Excerpt of its help is: "This tool alters the cumulative distribution function (CDF) of a raster image to match, as closely as possible, the CDF of a reference...

Dear Sophia, I am a bit annoyed at myself writing this in SAGA user forum, but I suggest to look to QGIS for some vector (shapes) operation like this. Using QGIS it can be done this way: Select by expression tool with an expression like $area < 100 to select small polygons (100 is the threshold size). Then; Eliminate selected polygons tool to merge small polygons with the adjacent polygons. In your case Largest Area method will do. Cheers, Kazuhito

Many thanks Olaf , (and everyone) Just reporting back that the suggested code really worked for me. Attached a file (Convert_Drainage_Route.xml), which interchanges Drainage Route grids between SAGA <=> GRASS <=> ArcGIS <=> WhiteBox formats (... single-flow only, unfortunately). Grateful if anyone can test this with a real-world example. I love SAGA!! All the best, Kazuhito
