Large images are split into multir-esolution representation

The files are padded to cover next power of two, and then

Naming of images for multiresolution representation

Uploading images into database

  • Either dice the large images first and store in .mrj (Multi-res JPEG) format and later read from the MultiResolutionJPEGSource and insert the binary tile chunk into database one by one.
  • Or Start the dicing process, and without any disk access, keep inserting into the MongoDB as and when every tile chunk is generated.

Upload to MongoDB

A simple mongo interface is created

<source enclose=pre lang="c">

  1. include <iostream>
  2. include <client/dbclient.h>

using namespace std;

class vtkMongoInterface {

   mongo::DBClientConnection conn;

public:

   // Constructor
   vtkMongoInterface()  {}
   // Operations possible
   int connect(const char *server = "127.0.0.1", int port = 27017);
   int insert(const char * name , int num );
   int insert(const char * path, mongo::BSONObj  obj);
   int query();

};

</source>
