Demo of Content Based Image Retrieval in python

Demo of Content Based Image Retrieval, implemented by Python and Tornado.

Image descriptors

• perceptual hash
• Otsu's method
• gray/RGB/YUV/HSV histograms
• GIST
• HoG and LSH (built by Kmeans clustering)
• SIFT and LSH (built by Kmeans clustering)
• Dense SIFT

Distance functions

• Hamming distance, or norm0 distance (L0)
• abs distance (L1)
• Eculidean distance (L2)

Simple re-ranking

• blending: mix results
• ensembling: weighted sum

Code structure

• util/: feature descriptors, feature and LSH preparation
• app/: http server, matching and retrieval
• templates/: html templates
• static/: datasets, js, css
• conf/: log.conf, and for feature data
• logs/: for log data
• settings.py: http port, common setting
• urls.py: server url path

Dependencies

• Tornado
• Image
• numpy, scipy

Run (Linux or Mac)

• cd util/pyleargist-2.0.5/lear_gist/ && make && cp compute_gist ../../ && cd -
• cd util && python prepare.py && cd -
• python main.py
• access http://localhost:19999/cbir

How to change dataset

• add a new image folder in static/dataset/
• in util/prepare.py, change dataset to the folder name, like dataset = 'ferrari'
• run as previous section

py-cbir's Issues

Error while running the code

I run the "cd util && python prepare.py && cd -" in one terminal and "python main.py" in another terminal.
After that I try to upload the image of a car then there is an error :

Traceback (most recent call last):
File "/usr/local/lib/python2.7/dist-packages/tornado-4.4.2-py2.7-linux-x86_64.egg/tornado/web.py", line 1467, in _execute

for line in open(pin):
IOError: [Errno 2] No such file or directory: 'conf/ferrari_gist.txt'

And in the terminal where i run main.py. Error is :

SyntaxError('unexpected EOF while parsing', ('', 1, 8957, '[0.10801810715592972, 0.002326306277452416, 0.002127562225475842, 0.0005990917825768668, 3.4315519765739386e-05, 0.0, 0.0, 0.0, 0.00547189558931186, 0.010420479502196192, 0.0015384791361639824, 0.0014970145497803806, 0.0010022991398243046, 0.00024735770497803805, 0.0, 0.0, 0.0008393004209370425, 0.001455549963396779, 0.0018701958272327964

Please help I am not able to figure out this error.
