Hello,i am doin a project on face recognition in opencv using Fuzzy Local Binary Patterns.For an image i am storing 64 regions with 255 bins for each region.the data is very large.can anyone suggest me the best way to retrieve such huge data fastly.i would be thankful if u help me.

64*255 is not that large.

retrieve from what ? and to where ?

are you trying to build a database and ask how to store it ?

Thanks for the replay. Actually i tried storing in .txt files but retrieving is taking long time. The values obtained during training need to be stored so that they can be compared while testing to recognise the test image(i think you are familiar with it). Now i have 241 trained subjects(6400 images).so i have 241 templates.i need to compare a test image with these 241 templates which is taking some can you suggest me a way which is fast to do so.

what are your fuzzy lbp patterns like ? if they are integer, you could just save your whole trained model as an image (png loss-less compressed, even).

Thay are fractions. Example: 27.0025, 31.3339, 30.5582, 36.9173, 21.7224, 25.9656, 24.9337, 31.1325, 19.3356, 22.2393, 21.4636, 25.6549, 19.1826, such(64*255) values.

i think some data is lost if we store as a image.

true, won't work.
