Localized Multi Texton Histogram

Content based image retrival using Localized Multi Texton Histogram.

In code block term localized is used to represent Blocks ps. the orientation from 0 ~ 360 is presented as 36 or nothing and orientations from 0 ~ 180 are presented as 18.

3 approaches are provided in the code:

1. MTH (By Original Author)
2. LMTH (Proposed)
3. MTH (Modified Using Canny => runs on approach 1)

Pre-requisite: You need to setup the databse before you can try out the code:

Create Database:
//============================ APPROACH 1 ============================

Command : CreateTextonDB ('path')
Example : CreateTextonDB ('/Users/Desktop/implementation/images/image.orig')

//============================ APPROACH 2 ============================

Command : BlockMTH_CreateBlockedTextonDB ('path')
Example : BlockMTH_CreateBlockedTextonDB ('/Users/Desktop/implementation/images/image.orig')

Command : BlockMTH_Canny_18_CreateBlockedTextonDB ('path')
Example : BlockMTH_Canny_18_CreateBlockedTextonDB ('/Users/Desktop/implementation/images/image.orig')

//============================ APPROACH 3 ============================

Command : Canny_36_Create_MTH_DB ('path')
Example : Canny_36_Create_MTH_DB ('/Users/Desktop/implementation/images/image.orig')

Command : Canny_18_Create_MTH_DB ('path')
Example : Canny_18_Create_MTH_DB ('/Users/Desktop/implementation/images/image.orig')

//============================ CREATE DATABASE CODE ENDS HERE ============================

SEARCH IMAGE:

//============================ APPROACH 1 ============================

MTH_SearchImage('imageName')

//============================ APPROACH 2 ============================

BlockMTH_Canny_18_SearchImage ('imageName') BlockMTH_SearchImage ('imageName')

//============================ APPROACH 3 ============================

Canny_36_SearchImage ('imageName') Canny_18_SearchImage ('imageName')

DEMO Trained database files are already setup and added to the repo:

1. MTH_Test1000_DB
2. MTH_Block_Test1000_DB.mat
3. MTH_Block_Canny_18_Test1000_DB.mat
4. MTH_Canny_36_Test1000_DB.mat
5. MTH_Canny_18_Test1000_DB.mat

Each approach uses its own dataset, for demo purpose you need to run the following command: BlockMTH_SearchImage ('433.jpg')
