Welcome to the Nanoparticles_app wiki!

Diagram, which shows, how algorithm works. algoritmus

Input:

Inputs are TEM images of gold nanoparticles and nanorods and .json file, which describes them. AuNP_20nm_001

Filtering:

I am using median filtering with kernel size dependent on image scale.

filtered_100

Binarizing:

I am using otsu thresholding method and combination of erosion and dilation for removing small holes and small objects (clearing image).

binarized

Watershed and Hough transform

First the program performs watershed algorithm with seeds from distance map. HT is performed on regions where NPs are overlapping.

AuNP_20nm_001
