Preparing Images for Analysis


Before starting and using eVe, you must first prepare the images upon which you want to perform visual searches. Preparing images consists of the following steps:


  1. Convert images to GIF, JPEG, or PNG format. The eVe analysis engine supports the following image types: GIF, JPEG, and PNG. If the images you want to analyze with eVe are stored as a different file type than these supported types, you must convert them to one of these types. To help you with any image conversions, the eVe SDK includes a third-party program called ImageMagickTM. This program allows you to resize, rotate, sharpen, color, reduce, and convert images.

  2. Resize images (optional). Before an image is run through the eVe analysis engine, that image will be automatically  resized (if needed) to match the value set in the maxResolution parameter of the file. However, if you first used ImageMagick to convert an image to a GIF, JPEG, or PNG format (see the previous section), we recommend you use ImageMagick to perform the resize, rather than allowing the automatic resize mechanism to perform the resize.


Performing these steps before analysis helps ensure a successful analysis and improved visual search results. For more information about how to prepare images for analysis, see the Additional Configuration section.
