how to process an image in knime with a Python script node?
from KNIPImage import KNIPImage from scipy import ndimage # Copy structure of incoming KNIME table output_table = input_table.copy() # Create empty output_column output_column = [] # Loop over every cell in the 'Img' column for index,input_cell in input_table['Img'].iteritems(): # get image from cell image = input_cell.array # apply some operation of image, here a Gaussian filtering filtered = ndimage.gaussian_filter(image, 3) # Write result back into a KNIPImage output_cell = KNIPImage(filtered) # Append output_cell to output array output_column.append(output_cell) # Set output_column in output_table output_table['Img'] = output_column
