Week 1: 5/12 - 5/16

- Set up computer; install software
- Familiarize myself with Matlab, having no previous experience
- Create Matlab exercise Q/A
- Become familiar with Adriane's progress and Emma's thesis Automated Writer Identification for Syriac Scribes

Week 2: 5/19 - 5/23

In Adriane's function processSyriacAnnotations.m, we saved the two structural arrays lftr and ldoc. lftr and ldoc are both structural arrays containing 14 fields which correspond to different letters in the Syriac alphabet. Each field is a cell array of various length, in which feature vectors describe a sample of that letter found in a manuscript. Inside each cell array, the first two indices indicate the character's global skew, while the rest of the indices in groups of 7 are feature vectors that describe each feature/cavity's 7 parameters of transformation (translation, rotation, elongation, and shear). At same index of each sample in ldoc is the string holding the source manuscript where the sample came from.

Here are screenshots from Matlab:

  • lftr


  • lftr.Alaph


  • lftr.Alaph{1,1}


Functions written:

  • runSyriacStyleComparison.m compares test features against sample features and ranks all sample sources in proximity to each test source. It takes 4 fixed parameters and 3 modification parameter (sampFtr, sampSrc, testFtr, testSrc + method, weights, letters). The four fixed parameters and the output rank are all structural arrays. The method parameter can be one of the three functions, simple vote, rank vote, or weighted rank vote. Users can pass in which method, which set of weights and which letters they want to use in the program.
  • filterManuscripts.m filters a set of sample features and their sources and returns a subset of features and sources corresponding to the given subset of sources.
  • identifyRepresentativeFeatureSample.m takes a cell array of sample features and returns the most representative sample feature and its index in the given array.
  • identifyRepresentativeSample.m takes a cell array of samples and returns the most representative sample and its index in the given array.

Functions in progress:

  • cleanSamples.m cleans samples of characters passed in as a cell array. The method of cleaning may be specified: ccTouch, selectLetters, predefined, predefinedFromFile. When using selectLetters method, users have the option to save (default empty string vs. a given directory) the masks generated for later use in the option to use predefined, which uses the latest masks saved. The default settings for cleaning: method = selectLetters; mask = ' ' (no mask); saveMasks = ' ' (don't save)

Week 3 & 4: 5/26 - 6/6
