roc-compare

Measure the similarity between galleries.

This command line application corresponds to the roc_compare_galleries function in the Application Programming Interface.

Options

Option	Meaning	Default
-b	Write a Binary Similarity Matrix	Write a text similarity matrix
–headers	Write row and column headers using the image file base names	Don't write row and column headers

Binary Similarity Matrix

By default similarity scores are written in tab-separated plain text. For large similarity matricies it is more efficient to store the scores in binary form. When -b is specified, the output of comparison will be an MBGC-compatible Similarity Matrix.

$ roc-compare -h 

Measure the similarity between two templates

Print the similarity between two templates faceA.t and faceB.t.

$ roc-compare faceA.t faceB.t 

Construct a similarity matrix

Write the pairwise similarity between all templates in facesA.t and facesB.t to similarity.tsv.

$ roc-compare facesA.t facesB.t similarity.tsv 

Construct a binary similarity matrix

Write the pairwise similarity between all templates in facesA.t and facesB.t in binary to similarity.mtx.

$ roc-compare -b facesA.t facesB.t similarity.mtx 

Construct a self-similarity matrix

Write the pairwise similarity between all teamplates in faces.t to self_similarity.tsv with row/column headers.

$ roc-compare --headers faces.t faces.t similarity.tsv 

Construct a similarity matrix to stdout

Print the pairwise similarity between all templates in facesA.t and facesB.t to stdout.

$ roc-compare facesA.t facesB.t > similarity.tsv
