DDIS - MATLAB Mex Version 1.0 (2017-02-21) Copyright 2006-2017 Itamar Talmi and Roey Mechrez Licensed for noncommercial research use only.

This code implements a fast Template Matching in the wild algorithm.

The algorithm solves the following problem: for each image I and a template T we calculate likelihood map of the template location in the image. We calculate the map using a raster scan over the image. DDIS (Deformable Diversity Similarity) used as the similarity measure between each sub window and the template. For more information see:

DDIS mex/C++ code: We provide rebuild mex functions in the bin folder, tested using MATLAB 2016a and VS12 (2013) If you need to rebuild and compile see Installation.txt inside the DDIS_code folder

• TreeCANN: kd tree Coherence Approximate Nearest Neighbor algorithm see [TreeCANN code] (provided under utils)

• MatConvNet: see [MatConvNet code]
• imagenet-vgg-verydeep-19.mat should be download from [[vgg]](http://www.vlfeat.org/matconvnet/models/imagenet-vgg-verydeep-19.mat and placed inside folder $\DDIS_code_matlab\utils\deepFeatures).
• FLANN: we find it hard to recomplie the project, we provide mex files. This is optional if L2 between deep features is desirable. Otherwise just use cosine distance.

To run one pair of images use

DEMOrun.m

to run on the entire dataset use

DEMOrunALLData.m

core functions:

• computeDDIS.m - using RGB patches
• computeDDIS_deep.m - using deep features patches
