- sparse coding
Q2: How SIFT is used?
SIFT is used in (all?) points of a letter to generate desxriptors. There are 100.000 descriptors overall before inputting into k-means. SIFT plays the main classification technique.
Q3: How did they produce the letter dictionaries?
Q4: What is sparse coding and its importance?
Sparse coding is to code documents (or any other codable thing) with a separating/descriptive code which shows also the similarity between items. An example might be bag of visuual words approach.
Q5: Are there any relevant techniques for our research?
This is relevant to divan-matching problem. This work might be cited in historical document matching. But it doesn't tell much that I don't know.
