Title:
AN APPARATUS AND A METHOD FOR SEMANTIC IMAGE LABELING
Document Type and Number:
WIPO Patent Application WO/2017/004803
Kind Code:
A1
Abstract:
Disclosed is a method for generating a semantic image labeling model, comprising: forming a first CNN and a second CNN, respectively; randomly initializing the first CNN; inputting a raw image and a plurality of predetermined label ground truth annotations to the first CNN to iteratively update weights of the first CNN so that a category label probability for the raw image, which is output from the first CNN, approaches the predetermined label ground truth annotations; randomly initializing the second CNN; inputting the category label probability to the second CNN to correct the input category label probability so as to determine classification errors of the category label probabilities; updating the second CNN by back-propagating the classification errors; concatenating the updated first CNN and the updated second CNN; classifying each pixel in the raw image into one of a plurality of general object categories; and back-propagating classification errors through the concatenated CNN to update weights of the concatenated CNN until the classification errors less than a predetermined threshold.
