[help-GIFT] Feature Extraction - Range breakdown

[Xavier Clements]

Greetings,

I have two questions, the first having two parts.

1. How does GIFT select features for extraction given that  I read in one of these discussions that the range of features extracted for any one 
image is between 341 to 3686? Is this upper limit arbitrary in nature and able to be altered in the code? 

2. Is the following breakdown of the 
ranges for each of the four extracted feature types correct (taken from a previous post)?
       
"1. color blocks

- 1st 256 times 16x16 color blocks, where each has 166 possible values 
 (i.e. features 0..42 495, where 0..165 are from the first block etc.)
- 2nd 64  32x32 blocks,
 (10 624 more feats, i.e. 42 496 .. 53 119)

- 3rd 16  64x64 blocks,
 (2 656 more, i.e. 53 120 .. 55 775)

- 4th 4  128x128 blocks
 (664 more, i.e. 55 776 .. 56 439)

2. color histogram
166 features
(feats 56 440 .. 56 606)

3. gabor blocks
- 256 times 16x16 blocks, each block containing 120 possible Gabor features
(features 56 607 .. 87 325 so that in 56 607..56 726 are the Gabors calculated
from the first block and in 56 726..56 845 are from the second etc.) 

4. gabor histogram
last 120 features ( 87 326 .. 87445 )"

Forgive this newcomer for potentially asking questions that have been previously answered (I looked through a number of the forum's archives...honest).

Thanks in advance,

Xavier
