Purpose¶

This sample program demonstrates how to:

Find blobs (objects or holes that have the same gray level range) in the image.
Keep only the blobs whose area is in a given range.

Code highlights¶

Define an image encoder to encode an image (m_Image) into an object ECodedImage2 (m_CodedImage).
```
EImageEncoder encoder;
encoder.Encode(m_Image, m_CodedImage);
```

Add the objects to an object selection object (EObjectSelection m_Selection).

// Select all the objects from the coded image
m_Selection.Clear();
m_Selection.AddObjects(m_CodedImage);

Filter the selection of objects by removing all objects whose area is outside the range [50, 10 000].

// Remove objects too small or too large
m_Selection.RemoveUsingUnsignedIntegerFeature(EFeature_Area, 50, 10000, EDoubleThresholdMode_Outside);

Draw the selected objects and their ellipse of inertia with their diagonals.

// Draw all the selected objects
CodedImage.Draw(drawAdapter, selection);

// Draw the ellipses of inertia with their diagonals, using a red pen
const ERGBColor redPen(255, 0, 0);
CodedImage.DrawFeature(drawAdapter, redPen, EDrawableFeature_Ellipse, selection, 1.0f, 1.0f, 0.0f, 0.0f, true);
