Subspace Learning Codes (Matlab) and Datasets for Face Recognition
We provide here some matlab codes of subspace learning algorithms, aswell as some datasets in matlab format. All these codes and data setsare used in our experiments. The processed data in matlab format canonly be used for non-commercial purpose.
If you have some problems or find some bugs in the codes, please email: dengcai2 AT cs DOT uiuc DOT edu
Learning algorithms
All the codes have been rewritten. You can download the old version at here .I am polishing the codes. If some files are missing, I am polishing them. Please wait some days...
- Some general functions
- EuDist2: Calculate the Euclidean distance matrix of two data matrix.
- ConstructKernel: Construct the kernel matrix.
- PCA: Principal Component Analysis
- KPCA: Kernel Principal Component Analysis
- LGE: (Regularized) Linear Graph Embedding (Provides a general framework for graph based subspace learning. This function will be called by LPP, NPE, IsoProjection, LSDA, MFA ...)
- OLGE: (Regularized) Orthogonal Linear Graph Embedding (Provides a general framework for graph based subspace learning (orthogonal basis vectors). This function will be called by OLPP. It is also very easy to develop ONPE, OIsoProjection, OLSDA, OMFA ...)
- TensorLGE: Tensor Linear Graph Embedding (Provides a general framework for graph based tensor subspace learning. This function will be called by TensorLPP. It is also very easy to develop TensorNPE, TensorIsoProjection, TensorLSDA, TensorMFA ...)
- KGE: (Regularized) Kernel Graph Embedding (Provides a general framework for graph based kernel subspace learning. This function will be called by KernelLPP. It is also very easy to develop KernelNPE, KernelIsoProjection, KernelLSDA, KernelMFA ...)
- LDA: (Regularized) Linear Discriminant Analysis (Generally, LDA can also use LGE as a subroutine. However, we can use the special graph structure of LDA to obtain some computational benefits.)
- KDA: (Regularized) Kernel Discriminant Analysis (Generally, KDA can also use KGE as a subroutine. However, we can use the special graph structure of KDA to obtain some computational benefits.)
- constructW: Function used to construct the affinity matrix.
- LPP: Locality Preserving Projection (You need to download LGE.m as well as constructW.m).
- OLPP: Orthogonal Locality Preserving Projections (You need to download OLGE.m as well as constructW.m)
- TensorLPP: Tensor Locality Preserving Projections (You need to download TensorLGE.m as well as constructW.m)
- KernelLPP: Kernel Locality Preserving Projections (You need to download KGE.m as well asconstructW.m)
- NPE: Neighborhood Preserving Embedding (You need to download LGE.m)
- IsoProjection: Isometric Projection (You need to download LGE.m)
- LSDA: Locality Sensitive Discriminant Analysis (You need to download LGE.m)
- MFA: Marginal Fisher Analysis (You need to download LGE.m)
Some popular face database in matlab format
All the faces are manually aligned, cropped and resize to 32x32 pixels.Each matlab data file contain variables ‘fea‘ and ‘gnd‘. ‘fea‘ is the data, each row is a sample (face); ‘gnd‘ is thelabel.
Yale database download Sample images Experimental results
Contains 165 grayscale images in GIF format of 15 individuals. Thereare 11 images per subject, one per different facial expression orconfiguration: center-light, w/glasses, happy, left-light, w/noglasses, normal, right-light, sad, sleepy, surprised, and wink.ORL database download Sample images Experimental results
Ten different images of each of 40 distinct subjects. For somesubjects, the images were taken at different times, varying thelighting, facial expressions (open / closed eyes, smiling / notsmiling) and facial details (glasses / no glasses). All the images weretaken against a dark homogeneous background with the subjects in anupright, frontal position (with tolerance for some side movement).PIE database, CMU download Sample images Experimental results
A database of 41,368 images of 68 people, each person under 13different poses, 43 different illumination conditions, and with 4different expressions.This dataset only contains five near frontal poses (C05, C07, C09, C27,C29) and all the images under different illuminations and expressions.So, there are 170 images for each individual.
The Extended Yale Face Database B download Sample images Experimental results
Please refer to this link for detailed information.For this database, we simply use the cropped images (which can be downloaded here) and resize them to 32x32 pixels.This dataset now has 38 individuals and around 64 near frontal images under different illuminations per individual.
Here are the databases with size of 64x64 pixels. (Matlab 7 or higher version is required to open these files)
