Introduction & Motivation 3

 Image matching  Automatically recognize whether two images contain the

similar content.  Comparing the image pixels as they are, will not work.

Comparing pixels of two regions (images are taken from Corel-database [1])

4

Challenges • Scale change, • Rotation, • Viewpoint variations, and • Illumination changes, etc.

Hence, the comparison using descriptor becomes necessary. 5

 Descriptors allow certain differences between the images.

Comparing using descriptor function (images are taken from Corel-database [1]) 6

 Image descriptor is being used in many applications [2], for

example:  Image Retrieval  Biomedical Image Analysis  Texture Classification  Image Correspondence  Face Analysis  Biometrics  Building Panorama  And many more…

7

Image descriptor

• Descriptions of the visual features • Described by appearance based characteristics such as color, shape, etc.

A descriptor must be

• Distinctive • Robust • Low Dimensional 8

 Issues 1. Where to compute the descriptors?  Over interest regions.  Interest region may be Grid [3], Key-Points [4 - 10] or Global [12-21] based.

Extracting regions using (a) Grid, (b) Key-points, and (c) Global approach [22]

2.

How to compute the descriptors?  Depends upon requirement.

3.

Similar ?

How to compare two descriptors?  Generally descriptors come with its similarity measure criteria.

 Local ordering based descriptor such as LIOP [7] –  Dimension increases exponentially with number of neighbors.

 In recent years, the local descriptors proposed [12, 14, 26] –  Did not explored the relationship among the local neighbors.  In some literature, it is explored at the cost of increased dimension [16, 25].

 The color descriptors proposed in the literature [18-20, 23, 34-56] –  The performance suffered due to lack of inter-channel relationship and robustness.

 Most of the existing illumination invariant methods [7, 12, 14] –  Fail in case of drastic illumination changes.

 The local descriptors with some pre-processing –  SOBEL-LBP [28] has used only two filters.  Performance may be further improved using multiple filters or other techniques.

Boosting the Performance of Local Descriptors with BoF and SVD

51

The framework of the proposed Content Based Image Retrieval (CBIR) system using Bag-of-Filters (BoF) and Local Binary Pattern (LBP).

The five types of filters used in this paper as the Bag-of-Filters, (a) Average filter, i.e. 𝐹1, (b) Horizontal-vertical difference filter, i.e. 𝐹2, (c) Diagonal filters, i.e. 𝐹3, (d) Sobel edge in vertical direction, i.e. 𝐹4, and (e) Sobel edge in horizontal direction, i.e. 𝐹5.

(a) An example image from Corel-1k database [44], (b-f) the image obtained after applying the 5 filters with mask 𝐹|𝑖=1,2,3,4,5 respectively over the example image of (a). 52

The performance comparison BoF-LBP descriptor with LBP, SLBP, SOBEL-LBP, LTP, LDP, LTrP, and SS-3D-LTP descriptors over Corel-1k, Corel-10k, MITVis-Tex and Stex-512S databases using ARP (%).

53

Proposed framework for NIR face retrieval using SVD and local descriptors.

54

Illustration of the sub-band formation (i.e. S, U, V and D sub-bands) from the SVD factorization [48] of any input PL using an example of size 4×4. • 𝐴 and 𝐶 are the 2×2 matrices containing the orthonormal column vectors, and • 𝐵 is a 2×2 diagonal matrix having singular values at the main diagonals 55

 Extracted the following descriptors – 

Local Binary Pattern (LBP) [12],



Semi-structure Local Binary Pattern (SLBP) [27],



Directional Binary Code (DBC) [29], and



Local Gabor Binary Pattern (LGBP) [51].

 The LBP descriptor computed over S, U, V, and D sub-bands are denoted as the SVD-S-LBP, SVD-U-LBP, SVD-V-LBP and SVD-D-LBP respectively.

56

Two widely adopted and benchmark NIR face databases, namely PolyU-NIR [49] and CASIA-NIR [50] is used for the face retrieval experiments.

 We have considered the set-1 of the PolyU-NIR face database which consists of the total

7277 images from 55 subjects.

 CASIA-NIR face database is comprised of the total 3940 images from the 197 subjects

having 20 faces each.

57

The performance comparison of the local descriptors (i.e. LBP, SLBP, DBC, and LGBP in the 1st, 2nd, and 3rd column respectively) over different sub-bands of the SVD in terms of the ARR (%) over PolyUNIR (in the 1st row) and CASIA-NIR (in the 2nd row) face database.

58

Retrieval results from CASIA-NIR face database using LBP (1st row), SVD-S-LBP (2nd row), SLBP (3rd row), SVD-S-SLBP (4th row), DBC (5th row), SVD-S-DBC (6th row), LGBP (7th row) and SVD-S-LGBP (8th row) descriptors. The first image in each row is the query face and rest images are retrieved faces. The faces in rectangles are the false positives. 59

Conclusions & Future Directions

60

 The interleaved intensity order reduces the dimension while consideration of more

number of local neighbors improves the discriminative ability.  The relationship of center pixel with its neighbors along with the relationship

among the local neighbors are exploited by LDEP, LBDP, LBDISP, and LWP.  The diagonal neighbors, bit-planes and wavelet decomposition are making the descriptors

more discriminative while the dimensions are very low as compared to the state-of-the-art descriptors.  The color quantization based descriptors LCOD and RSHD are rotation and scale

invariant.  These descriptor are more suitable for the color natural databases.  The dimension of these descriptors is also very reasonable.

 The multichannel decoded local binary patterns maLBP and mdLBP have shown

the great improvement in the retrieval performance over color texture databases.  The dimension of these descriptors is relatively high but still low as compared to some

recently introduced descriptors.

61

 The illumination compensation mechanism are useful for both uniform as well as

non-uniform illumination.  It can be used as a pre-processing in many applications.  It has also been noticed that the results of illumination invariant descriptors improved with

illumination compensation.  The performance of local descriptor such as LBP has been improved significantly

when applied with the BoF in CBIR over the gray scale natural and textural databases.  The performance of local descriptors are improved when extracted over S sub-band

of SVD. The local descriptors with SVD have been experimented over the NIR face databases under

image retrieval framework and observed satisfactory performance.  The use of SVD with local descriptors does not affect the size of the local descriptors.

62

 The region based descriptors mostly designed for the gray scale images; it

can be explored for the color images also.  The performance of local descriptors can be further improved by utilizing

the local neighborhood information more effectively.  The color descriptors are still having the dimensionality problem which can

be tackled further.  The sensitivity to the illumination problem of color descriptors can be

explored to introduce more illumination robust descriptors.  The performance of descriptors proposed for the one type of images can be

explored with the other kind of images.  Nowadays, deep learning is being used very actively to develop the

features at the intermediate layers. This may also one of the future works to work with descriptors and deep learning. 63
