Description

This function retrieves the results for a specified feature of one or all included blobs, from the specified Blob Analysis result buffer.

If your target image was associated with a camera calibration context, positional and dimensional results are, by default, returned with respect to the relative coordinate system of the image. Otherwise, these results are returned in pixels, relative to the top-left pixel in the target image.

If your target image was associated with a camera calibration context but you want to retrieve positional and dimensional results in pixel units, use MblobControl() with the M_RESULT_OUTPUT_UNITS control type set to M_PIXEL. Note that if you set M_RESULT_OUTPUT_UNITS to M_WORLD without having specified a calibrated image from which to calculate the results, MblobGetResult() will generate an error.

When calculated in pixel units, the pixel aspect ratio, specified using MblobControl() with M_PIXEL_ASPECT_RATIO, is taken into account horizontally. Results are returned in units of "pixel height" since the pixel width is adjusted to be equal to the pixel height.

Note that MblobGetResult() generates an error if you try to retrieve a result whose corresponding feature, or the group of features to which it belongs, was not enabled for calculation. You can add the M_AVAILABLE combination constant to a feature to determine if the result is available for retrieval.

Note that this function reference has not been updated for a MIL system added during a MIL update. Refer to the MIL system's release note to see if there is complementary information.
Parameters
This function is not supported on the selected boards.

Retrieves the compactness of each blob. This is the ratio between the area of a circle with the same perimeter as the blob in question, and the area of the blob itself.

This is due to the effect of square pixel discretization. The more convoluted the shape, the greater the value.

The formula used is equal to where A is the area of the blob and p is the perimeter of the blob.

Click to summarize M_EULER_NUMBER +

Retrieves the number of blobs minus the number of holes (number of blobs - number of holes). This value is more useful if calculated using the M_WHOLE_IMAGE blob identification mode instead of the M_INDIVIDUAL blob identification mode. Unlike its usual effect, when using the M_WHOLE_IMAGE blob identification mode, each blob is treated individually, as opposed to grouping all of the blobs in an image together. So M_EULER_NUMBER returns (number of blobs - number of holes). Whereas as usual, when using the M_INDIVIDUAL blob identification mode, each blob is treated separately; therefore, the Euler number for each blob is just 1 - the number of holes. The calculation of this feature can be enabled using MblobControl() with M_EULER_NUMBER.

This result is not affected by the setting of M_RESULT_OUTPUT_UNITS.

It is accurate for reasonably compact objects, but becomes less accurate for very elongated objects (because M_FERET_MIN_DIAMETER becomes less accurate). For very elongated objects, M_ELONGATION should be used.

Combination value		 Description
Click to summarize M_FERET_CONTACT_POINTS_X1

Retrieves the X-coordinate for the first contact point of the Feret diameter of each blob.

If you requested to retrieve results in world units with M_RESULT_OUTPUT_UNITS and the calculation was performed on appropriate buffers, the results returned are transformed into the relative coordinate system, taking into account distortions as best as possible.
