For a complete list of the methods available with Fiji see the Plugins section located in the Documentation section under the Content tab at the top of this page. These include Otsu's thresholding, maximum entropy threshold, and mixture modelling thresholding. (2004), "Survey over image thresholding techniques and quantitative performance evaluation.", Journal of Electronic imaging 13(1): 146-168 ( on Google Scholar).įiji has several plugins found in the menu Image › Adjust › Threshold for automatic calculation of an image threshold. You will use the manual tracking plugin in Image) to record the time, position, and velocity of the spheres in each frame of your video. An evaluation of over 40 of these can be found in this paper: There are many algorithms you can use to calculate the threshold without introducing user-bias. The image can be converted to a binary image via the menu command Image › Type › 8-bit. The background of the thresholded image can be made light or dark. The Color space option allows you to choose between HSB, RGB, Lab, and YUV. The Threshold color option allows you to choose between Red, White, Black, or B&W as the thresholding color. The Thresholding method option allows you to choose a thresholding techniqe other than the default. It does not store any personal data.For color images, setting the threshold is done with the command sequence Image › Adjust › Color Threshold.

Using groups is convenient for house-keeping, plus the track manager has some nice options to work with groups, be sure to check them out. You have successfully tracked your object!ħ) Repeat steps 2-6 to add a new track to the same group (a group may have as many objects as you want)Ĩ) Repeat steps 1-7 if you have another group of objects (e.g. As you click, the viewer automatically moves to the next frame, waiting for your next click.Ħ) Click the Stop button on the interface.
A Track Manager window will automatically pop up and display your tracks live as you create them.ģ) Browse for the first time point where you wish to start a track.Ĥ) Adjust the slice (if you are in 3D) and click on the center of your object. The procedure is as follows:ġ) Type the name of the group of tracks you wish to create (don't forget to hit the return key to validate the new name).Ģ) Press the Start button on the interface. The plug-in currently has a minimalistic interface (be sure to add your requests via the ratings!). Its functionalities are pretty basic: it lets you click manually in the center of the object of interest for every time point, and integrates with Icy's great Track Manager so that you still benefit from advanced management and measurements of the tracks.
This is where the Manual Tracking plug-in kicks in.
Well, for all of these cases that drive you mad, you can always temporarily rely on a manual option, either because you are running late on a deadline, or until your favorite collaborator finds a way to improve the detection (or tracking) algorithms (if you haven't found one yet, take a minute to send a sample on the support forum). Like to do things old-school? Track your objects manually, the Icy way!ĭocumentation Automated tracking is the future, so why use manual?!Īutomated tracking is on its way, highly motivated by strong arguments such as the need to handle huge data sizes, diminish user bias, produce large reliable statistics etc. Yet, despite the great solutions available out there (including Icy's powerful Spot Tracking plug-in), how many times have you cursed because they seem to just not want to work on *your* specific data set, usually because the objects are hard to detect to begin with, and that causes the best trackers in the world to just break down.
