Bug in Detect blobs
In builder, using Detect Blobs with Static threshold, the sensitivity value has no impact. Tried setting it to any setting between 0.1 and 0.99, with Dynamic threshold it works. If it is not intended to work with static threshold, perhaps the option should be removed.
Running beta 6, using it on both a binarized image, an RGB image and a BW image, same result.
@aalamaki Another bug as well, the invert option in Find threshold is grayed, cannot be changed to true. Running the builder on Windows 10.
3rd little issue that I noticed, when using Mask color, maskedColor has only option to mask in RGB even though we have done conversion of the image to Greyscale. Should be able to mask in BW as well.
Yet one more bug, writing it all in this same as there are a couple. In any tool, if I click the "unpin" on a image input/output and stretch it over the image, have to be very careful not to pull it over the display because the only way to close the picture is from the upper right corner of the image and if you stretch the image, this easily goes out of the canvas area.
Not even able to scroll to make it visible, please see what I mean. Also clicking on bottom right on the resize does not help, it just resizes the canvas but not the unpinned image, Could not find any other way to close the image, a button combination like Control-D could be useful or an option to close the picture when right-clicking on it.

Thanks for the reports. To be able to verify and fix issues we need to know the exact steps you took to trigger a bug. Now, I'm not quite sure if I understood your situation correctly. However, here's how I see it:
- The sensitivity parameter is documented to have an effect only in the dynamic thresholding mode here: https://doc.visionappster.com/3.0-beta6/tools/detectblobstool/#detect-blobs. Some tools have input parameters that have an optional effect. They don't however disappear to avoid breaking connections.
invertin Find Threshold is an output parameter (function return value). It is calculated from input data and cannot be manually changed.
- You mean the Mask Image tool? RGB triplets can represent gray levels, and the tool does the RGB->gray conversion automatically. Did you try it? Is the output incorrect?
- This looks like a genuine bug. We were however unable to reproduce it. Can you send us the exact steps?
