DPM deformable part models release5

The new Code comes out.

 

What's changed since voc-release4?

Voc-release5

---

The main highlights in this release:

 

* Weak-label structural SVM (WL-ssvm)

Thelearning code has been generalized to support both lsvm and

Wl-ssvm.By default lsvm is used for training Mixture Models

Andwl-ssvm is used for training the person grammar model from [1].

 

* Person grammar model [1]

Theperson grammar model from [1] is implemented in the person_grammar

Directory.

 

* Optimization improvements

Thestochastic subgradient descent solver (learn. CC) has been replaced

BYL-BFGS (using Mark Schmidt's minconf Package). The learning and

Featurevector cache code has been completely rewritten from scratch.

Notably, the feature vector cache is now stored in memory and not

ALarge file on disk. The memory requirements are slightly higher

Before, but your disk will thank you.

 

* Code cleanup, reorganization, and speedimprovements

Thegrammar API has been simplified and streamlined. The Code has been

Organizedinto subsystems. training models is faster. For reference,

Apascal VOC 2007 bicycle model can be trained in 2 hours on a 4-year-old

Quad-coremachine (using 'pool open 8 ').

 

* Scale prior

Grammarproductions now have learnable "scale prior" parameters that

Helpcalibrate detection scores at different scales. In conjunction

This, the feature pyramid Code supports adding an extra octave of hog

Featurescomputed on 2x2 pixel cells (off by default ).

* Bug fixes

Severalbug from voc-release4.01 (mostly involving memory usage) have

Beenfixed.

 

* New Configuration System

Theglobals. m configuration file has been replaced by voc_config.m.

Thispermits overriding configurations by setting a global variable.

Suchconfiguration overriding makes it easy to test different config

Optionson different machines from the same code directory
