Versatile Framework for Medical Image Processing and Analysis with Application to Automatic Bone Age Assessment

Algorithm 1

Proposed deep AL framework.
Input:
: initial labeled training data, composed of samples;
: initial unlabeled training data, composed of m samples;
: committee of medical image segmentation networks to be trained;
Output:
: trained committee of medical image segmentation networks
Repeat:
1. Train with the loss function in equation (4) on the labeled data.
2. Calculate the dissimilarity of each sample in U among every member in C and select the data with the larger dissimilarity.
3. Oracle is queried to annotate the data selected in step 2 and add the annotated sample to L.
4. Update U and L.
Until:
The is converged to a satisfied result.
