edge detection example on EVE simulator

mohammed zakariya ansari
Expert 1135 points

VGA_out.y.txtcustomImage640x480.raw.txtVGA.y.txtcustomImage_output640x480.raw.txtHi Champs,

I am using CCS 5,4 for EVE simulator. its getting compiled and i tried to run the morphology testcase, it worked fine.

Now i wanted to check with edge detection using sobel. Below are my steps. changed the file extension to upload as .txt. please  remove .txt to see the content

  1. update the "config_list.txt" please find attached
  2. update "edge_detector_random.cfg" please find attached.
  3. i commentated the code that was supposed to be in so that it shall generate the output file. enable "ENABLE_OUTPUT_DUMP" in edge_detector_tb.c
  4. launch simulator ,provide the .elf file and run the the simulator and wait for out to be generated.
  5. i used reference image that comes with the package and other, my results remains the same.
  6. PFA console log,input and out images. screen for input and output image.

Do help me if i am off the track or shall i use different steps to move forward.

Thanks,

Mohammed

    Hi Mohammed,

        Have you tried changing the threshold (EDGE_DETECTOR_TI_InArgs.threshold1)? Btw its not a very good idea to run full application on simulator as it could be really slow. Instead I would suggest you to use host emulation. It would be much faster and easier to work with.

    Regards,

    Anshu

    Thanks Anshu for quick reply,
    I have not changed threshold1. Do you want me try this? let me know what will be the best suitable threshold1 please.
    Surely i will go with emulation , i am trying to build it parallel will come to bug you for emulation problems i am facing in different thread. :) .

    Hi Mohammed,

       You can try multiple threshold starting with very small just to rule out if the problem is because of thresholding or with something else.

    Hi Anshu,

    I am trying different threshold but havent got any luck yet. i guess threshold may not be affecting the output dump.

    Anyway...

    please suggest more options so that i can try parallel along with threshold change.

    Thanks,

    Mohammed

    Lets go back to your list of steps :

    update the "config_list.txt" please find attached >> This is ok
    update "edge_detector_random.cfg" please find attached. >> I couldn' t find this in your attachment.
    i commentated the code that was supposed to be in so that it shall generate the output file. enable "ENABLE_OUTPUT_DUMP" in edge_detector_tb.c >> Do you mean you commented #define ENABLE_OUTPUT_DUMP 0 line?? You should set it to 1 instead. #define ENABLE_OUTPUT_DUMP 1
    launch simulator ,provide the .elf file and run the the simulator and wait for out to be generated. >> This is ok
    i used reference image that comes with the package and other, my results remains the same. >> I couldnt get this point

    please find my response inline;

    update the "config_list.txt" please find attached >> This is ok
    mohammed: this is same.
    update "edge_detector_random.cfg" please find attached. >> I couldn' t find this in your attachment.
    mohammed: i have changed cfg.txt,no problem, please see below the content of the file.

    mohammed: i did the same like ENABLE_OUTPUT_DUMP 1.
    launch simulator ,provide the .elf file and run the the simulator and wait for out to be generated. >> This is ok
    ENABLE_OUTPUT_DUMP 1: this is ok.
    i used reference image that comes with the package and other, my results remains the same. >> I couldnt get this point
    mohammed: i had image "customImage640x480.raw" comes with the package. apart from this i have couple of more images from internet.one is VGA image and one is .bmp.

    one more thing when i set threshold1 =5 and comment out the image processing in dump section of the code in the file "edge_detector_tb.c" , i see some distorted data, please find attached input and output images.

    What pitch you are using for the output?
  • 0 in reply to Anshu Jain
    Expert 1135 points

    I am not changing the pitch for input or output, it same as defined in .cfg file (outputPitch = 640)

    Does the testcase passes for your test image? If yes then can you share your config file along with image you are running. I can try running at my end to see what output I am getting. Btw which version of EVE SW are you using?
  • 0 in reply to Anshu Jain
    Expert 1135 points

    I am using EVE SW version "eve_sw_01_18_00_00" .

    my testcases passes with the image. please find attached input image. PLEASE REMOVE THE .txt EXTENSION BEFORE USING THE IMAGES. I CHANGE THE EXTENSION TO UPLOAD THE FILE BECAUSE FILE IS NOT GETTING UPLOADED TO TI FORUM.

    config file contents are same as mentioned above in thread

    Hi Anshu,

    Any luck on this please?

    Thanks,

    Hi Mohammed,

      I found the issue. The problem is in the dumping logic. Currently it is dumping assuming the output is of Canny Edge detector and hence it is converting the output to be in better for human visual ( instead of 1 and 0 it is converting them to 255 and 0). But Sobel output is already in this format ( 255 and 0) so no need of this conversion. Can you just dump targetOutputImage instead of edgeImage at line 1109.

    Regards,

    Anshu

    Do you mean to bypass the for loop? i tried that bypassing the for loop...
    OR
    Do let me know what shall i try from below code snippet;
    #if ENABLE_OUTPUT_DUMP
    if ( strcmp((const char *)testcaseParams[testcase].outImage, ""))
    {
    uint8_t * edgeImage = NULL;
    uint8_t * targetOutputImage;
    targetOutputImage = (uint8_t *)outBufs.bufDesc[EDGE_DETECTOR_TI_BUFDESC_OUT_IMAGE_BUFFER]->bufPlanes[0].buf;
    edgeImage = (uint8_t *)malloc (testcaseParams[testcase].outputPitch *testcaseParams[testcase].imageHeight);
    if ( edgeImage == NULL )
    {
    TEST_PRINTF("Fail to allocate edge image for dumping\n");
    goto EXIT_LOOP;
    }

    for ( j = 0 ; j < testcaseParams[testcase].imageHeight - 2 ; j++)
    {
    for (i = 0; i < numBytesToCompare; i++)
    {
    if ( targetOutputImage[i + j * testcaseParams->outputPitch] == 1 )
    {
    edgeImage[i + j * testcaseParams->outputPitch] = 255;
    }
    else
    {
    edgeImage[i + j * testcaseParams->outputPitch] = 0;
    }
    }
    }

    TI_FILE * fp = FOPEN((const char *)testcaseParams[testcase].outImage,"wb");

    if(fp == NULL)
    {
    TEST_PRINTF("Failed to open output file: %s.\n", testcaseParams[testcase].outImage);
    return -1;
    }

    FWRITE(edgeImage, testcaseParams[testcase].outputPitch *testcaseParams[testcase].imageHeight, 1, fp);

    FCLOSE(fp);

    if ( edgeImage )
    {
    free(edgeImage);
    }

    }

    endif.

    Thanks,
    mohammed

    Instead of following line
    FWRITE(edgeImage, testcaseParams[testcase].outputPitch *testcaseParams[testcase].imageHeight, 1, fp);
    use
    FWRITE(targetOutputImage, testcaseParams[testcase].outputPitch *testcaseParams[testcase].imageHeight, 1, fp);

    Thanks Anshu, It helped.
    I had a workaround for this as, i called th FWRITE right after test: at line 964.

    Thanks for logical advice/reason, i have not thought from that point. i was wondering if something wrong from my-side. :)
