  1. Using opencv with Kinect for azure

    k4a_image_t depth_image = k4a_capture_get_depth_image(capture);

    color_frame=cv::Mat(k4a_image_get_height_pixels(color_image), k4a_image_get_width_pixels(color_image), CV_8UC3, k4a_image_get_buffer(color_image));

    cv::imshow("color", color_frame);

    The imshow here creates a 'segmentation fault' even though there are proper values in the matrix. I check this is not an opencv fault. Could someone please help to visualize color and depth data from custom application.

  2. Bug: color JSON from REST API contains both "isBwImg" and "isBWImg" (Typo)

    There is a little bug in the JSON response from the REST API:

    In the JSON response, the color object contains two most-likely identical features with different names - "isBWImg" and "isBwImg" (lower-case "w" vs. capital "W").

    Ex:

    "color": {
    "dominantColorForeground": "White",
    "isBwImg": false,
    "isBWImg": false,
    "accentColor": "228AAA",
    "dominantColorBackground": "White",
    "dominantColors": ["White"]
    }

  3. Capturing PO number Issue

    Hello Azure Team,

    Using azure online tool , the attached image generates the correct json response(all image text), but when we use it via computervision, cognitiveserive API in web or mobile Android it returns less/incorrect json response which is invalid and we cannot pick number from it.

  5. Computer vision algorithms applied to a video or stream

    Could it be possible to use this algorithm with a video stream instead of single images

  6. Support data URIs in image APIs (vision/emotion/face)

    For JavaScript clients, there are many circumstances when you want the image as represented in a Canvas to be uploaded to one of the MCS APIs that accept images. The problem right now is that Canvas returns its content in the form of a data URI (RFC 2397), and callers need to convert this to a blob before uploading. It would be convenient if the APIs simply accepted the data URI directly, although it would mean the network payload is larger than need be (because of the base64 encoding.)
