How to Use NDTBatch in an Assignment

If you need some help with your Matlab assignment then there is a Neural Network Toolbox that can help. The toolbox can be found under the MATLAB category and it is called NDTBatch

NDTBatch is a program to load a set of example image sets or pre-made images. Once you have loaded these into the NDTBatch program, you can use a simple interface to make adjustments in the image.

Another component of the NDTBatch toolbox is the imagelist. The imagelist allows you to enter all of the individual image sequences which will later be assembled into an image. For this, you will need to generate a text file of the sequence names, they will be useful later in the sequence hierarchy. The method for generating the sequence names is to open up the Image Tools option in the NDTBatch Options and drag and drop the image files onto a new text file.

Now that you have created the sequence names and saved them in a text file you will need to use the matrix application in the NDTBatch Options to input each image individually. This can be done with the image picker which is located on the left hand side of the matrix application bar.

Now that you have correctly inputted each image into the matrix, you will want to run the image picker again. From here you can manually select the sequence you want. There are some additional options available for the sequence. The sequence labels are also available in the matrix menu.

Each sequence can be individually put into its own label. Once the sequence is added to the matrix it will appear in the text file. You can also have the sequence labels be centered with respect to the image file if you like.

The matrix selector will allow you to rotate the rows and columns in any way you desire. If you do not see the option for rotation in the matrix selector then you can also select the array rows and columns from the matrix select menu. You can also have the matrix selector work with a grid.

If you do not like any of the individual values for the matrix selector then you can use the context menu to make them a default value. In the matrix selector you will find a menu item called make default. By clicking on this option you will give the respective values a default value and this is useful if you know exactly what you want and do not want the variance when working with the selection.

If you do not like the matrix selector then you can use the settings menu to change the default selection to be whatever you want. To see what these settings do, click on the settings icon in the matrix selector.

Once you have made your desired changes in the matrix selector you can use the matrix toolbox. The matrix toolbox allows you to add a matrix style by moving the cursor over the matrix in the matrix selector and then using the arrow keys. It will add a color based matrix style, these will be listed as ‘no style’.

To add an image to the matrix, you will use the ‘add’ command. Simply select the image using the mouse and then click on the ‘add’ button. Alternatively you can use the image picker in the matrix toolbox to select an image and then click on the ‘add’ button.

If you want to remove an image, then use the same method as you did to add the image. Simply select the image and then click on the ‘remove’ button.
