Image Analysis Results

Note that if your image contains analysis results, the analysis results are deleted when you execute this function.

Lightfield 4D Raw Data

If you want to use the function with unprocessed Lightfield 4D raw data, you must not extract single phases but have to extract all phases. Lightfield 4D processing always needs the data of all phases (lenses). Additionally, if you want to extract a region, Lightfield 4D raw data images need a minimal region size. A message is displayed in the tool in both situations to indicate the appropriate setting.

This method allows you to extract parts from one image and use these to create a new image. You can select these parts freely from the individual dimensions of the image. Each of the parameter sections is only visible if the corresponding dimension is present in the input image.

Parameter

Description

Channels

Selects which channels of the input image are used. All channels are selected by default. To deselect a channel, click on the respective channel button.

Z-Position, Time, Block, Scene, Phase

Here you can select which parts of the input image you want to use for the resulting image.

-

Extract All

If selected, all parts of the corresponding image are extracted.

-

Extract Single

If selected, you can select a single image to be extracted.

-

Extract Range

If selected, you can select a certain range of images to be extracted.

-

Extract Multiple

If selected, you can select several continuous ranges and individual sections.

Enter one or more sections that you want to select in the input field. To do this, enter the first section, followed by a minus sign, and then the last section. If you want to define an interval, after the last section enter a colon and then the interval. The entry "2-10:2" means that every second section is selected from section 2 to section 10.

Enter a comma after the first section if you want to define another section. You can also select individual sections separated by commas. By entering "2-10:2,14-18,20,23", you select every second section from section 2 to section 10, followed by sections 14 to 18, as well as sections 20 and 23.

-

Get current position

Adopts the position from the current display in the image area.

-

Interval

Activated: Interval mode is active. The Interval spin box/input field appears.

Enter the desired interval here. E.g. if you enter the value 2 only every 2nd value from the range is considered.

Region

Here you can select if you want to use the entire image or just a region (ROI) of the input image.

-

Full

Select this option to use the full image for the new image.

-

Rectangle region (ROI)

Select this option to draw in a rectangle region of interest, which will be used for creating a new image.

If a rectangle region was drawn in, you can see and change its coordinates by editing the X/Y/W/H input fields.

-

Keep tiles

Only has an effect, if a region (ROI) is defined.

Activated: Extracts the drawn in region including the complete tiles. This setting is recommended when you want to apply DCV processing functions on the resulting image.
