Promblems about RxImageLink & TxImageLink

  • Hello Lily,

    i'm not an Expert but i might see a little mistake so far.

    The sync operator waits for an image on both inputs. While the sync waits there will be no image at the Tx image link. Also no image at the Rx image link. So the Sync will wat forever. Deadlock.

    Try to add a first dummy image/pixel parallel to the Rx image link operator. So the sync will recieve an input for the first iteration and from the second on the Rx Link provides the next.


    i attach an example i used for something similar.

  • Dear Robert,

    Thanks for your quick reply. I got it.

    Another little question I need your help. How to get the line from Row-0 to Row-N one by one line from one image when we simulate the processing cycle for N times. I tried to use ImageBuffe/ ImageFifo/Register and select line buffer but it only output the first line everytime. Woul you pls. help to handle this?

    Another question is how to change the Image from 1D to 2D?

    Thanks a lot!

  • Hello Lily,


    i hope this may help you.

    Try to use the operator "SplitImage" and limit the image height to one Line. The Format Valt_1D or Valt 2D is free to choose after this operator.

    For the little example i atteched the result will be all lines one by one.

  • Hi Robert,

    Thanks for your suggestions. I also tried to use the operator SplitImage. It will split the image into 1024 lines one by one together when we simulat the process for one time. If we simulate the process on second time, it will run this process again. I'm afraid it will use more resources of the system.

    And actually we need to get only one line when we run this process once. Then we get the second line when the process goes on the sceond time. And so on. It will be used in our process for cyclic operation and also need so much resources. Do you think it's possible or not?

  • Hello Lily,


    oh i got it. Sure SplitImage uses the complete input image to guide line by line further. When the simulation is started all lines got simulatet before stoping so its not neccessary to start different cycles.

    In Reference to the design in the first post it's possible to simulate all ines at once and watch in the probes what happend from line to line.


    If you want to use diffrent Input images and select lines from the diffrent inputs or selct some lines from an example image then im afraid this operator alone wont work.

    I'm afraid i don't really know how to stop and start the simulation for every line. A workaround might be to insert Lines as sources instead of a complete image.


    Meybe the SiSo support can provide a good hint.

  • Dear Robert,


    Thanks for your kindness and help. And What's the meaning of "Meybe the SiSo support can provide a good hint."?

    Another question: We got the CenterX & CenterY of all the objects After the blob analysis. If we want to combine two or more closed objects. Do you think is it possible to realize it through comparing the D-value of each CX & CY of all the objects? How to get the D-value of each pixel of one line?


    Greetings Lily
