Component
MatlabOpExecutes a Matlab script that generates an image directory from given image directories. You can either modify a single source of images or combine up to five sources. The source directories must contain the same number of images. The source images can be referenced as im1 and im2 (etc.) in the script. The component expects the resulting image to be in imout and/or imout2 variables. If you want to generate images without sources, specify the parameter files.
If tableout variable is present, it will be written as a csv file table output port. Note the special struct format of the variable! (see testcases).
Example:
| Sources | Output |
|---|---|
  Source script: "imout=xor(im1,im2);" |

| Usage | Example with default values |
Inputs| Name | Type | Mandatory | Description |
|---|---|---|---|
| command | MatlabSource | Optional | Matlab script file to operate the images with. The string parameter will override this input. |
| table | CSV | Optional | Optional CSV file to read. Will appear as table. |
| in1 | ImageList | Optional | Source images 1 (in1). The output images will be named after this input folder, or if not defined, after the first array input folder. |
| in2 | ImageList | Optional | Source images 2 (in2) |
| in3 | ImageList | Optional | Source images 3 (in3) |
| in4 | ImageList | Optional | Source images 4 (in4) |
| in5 | ImageList | Optional | Source images 5 (in5) |
| inArray | Array<ImageList> | Optional | An array of directories with image files. (ina1, ina2, ...) |
| file1 | ImageList | Optional | Source image 1 (file1). This folder should contain only one image. The same image is used in each iteration of dir1. |
| file2 | ImageList | Optional | Source image 2 (file2). See input file1. |
Outputs| Name | Type | Description |
|---|---|---|
| out | ImageList | Result images (out) |
| out2 | ImageList | Result images (out2) |
| tableOut | CSVList | Result tables (tableout) |
Parameters| Name | Type | Default | Description |
|---|---|---|---|
| extension | string | "" | String to be added after the output filenames. e.g. ".png" to change the image format |
| files | float | 0 | If there are no input folders, this number is used as the number of files generated. The resulting files will be named file1[extension], file2[extension], ... Use the variable file in the script to get the file number. Remember to use extension when using this parameter. |
| param1 | string | "" | Value of this parameter will be assigned to param1 variable |
| param10 | string | "" | Value of this parameter will be assigned to param10 variable |
| param2 | string | "" | Value of this parameter will be assigned to param2 variable |
| param3 | string | "" | Value of this parameter will be assigned to param3 variable |
| param4 | string | "" | Value of this parameter will be assigned to param4 variable |
| param5 | string | "" | Value of this parameter will be assigned to param5 variable |
| param6 | string | "" | Value of this parameter will be assigned to param6 variable |
| param7 | string | "" | Value of this parameter will be assigned to param7 variable |
| param8 | string | "" | Value of this parameter will be assigned to param8 variable |
| param9 | string | "" | Value of this parameter will be assigned to param9 variable |
| script | string | "" | Matlab script string to operate the images with. This parameter overrides the input script file. |
