Real-time image search by CNN Model and K-D Tree

Image_Search_by_CNN_and_KD-tree

Search similar images.The similarity between images are modeled by CNN (Convolutional Neural Networks) model.Real-time search by K-D Tree.

Executing

Please refer to code/readme.txt for running

Visulaization of Images

Images are plotted by feature values

2--1-

Search System (CNN model + K-D tree)

1--1-

Input image and return top-k similar images

Image similarity by features of CNN model
Each image is represented by feature values of the-sencond-to-last FC layer
(the last FC layer outputs labels)

Index by K-D tree
Each image is indexed by its feature values by K-D tree.
Build index: n*log(n)
Search: log(n)

To search for more types of images, we should use more different and new images to train models.
