Detailed Documentation

Represents a blob that contains three planes (Y,U and V) in I420 color format.

Typedefs

typedef std::shared_ptr<I420Blob> Ptr

A smart pointer to the I420Blob object.

typedef std::shared_ptr<const I420Blob> CPtr

A smart pointer to the const I420Blob object.

Construction

I420Blob(const Blob::Ptr& y, const Blob::Ptr& u, const Blob::Ptr& v)

Constructs I420 blob from three planes Y, U and V.

Parameters:

y

Blob object that represents Y plane in I420 color format

u

Blob object that represents U plane in I420 color format

v

Blob object that represents V plane in I420 color format

 
I420Blob(Blob::Ptr&& y, Blob::Ptr&& u, Blob::Ptr&& v)

Constructs I420 blob from three planes Y, U and V.

Parameters:

y

Blob object that represents Y plane in I420 color format

u

Blob object that represents U plane in I420 color format

v

Blob object that represents V plane in I420 color format

Methods

Blob::Ptr& y()

Returns a reference to shared pointer to Y plane.

Please note that reference to Blob::Ptr is returned. I.e. the reference will be valid until the I420Blob object is destroyed.

Returns:

reference to shared pointer object of Y plane

const Blob::Ptr& y() const

Returns a constant reference to shared pointer to Y plane.

Please note that reference to Blob::Ptr is returned. I.e. the reference will be valid until the I420Blob object is destroyed.

Returns:

constant reference to shared pointer object of Y plane*

Blob::Ptr& u()

Returns a reference to shared pointer to U plane.

Please note that reference to Blob::Ptr is returned. I.e. the reference will be valid until the I420Blob object is destroyed.

Returns:

reference to shared pointer object of U plane

const Blob::Ptr& u() const

Returns a constant reference to shared pointer to U plane.

Please note that reference to Blob::Ptr is returned. I.e. the reference will be valid until the I420Blob object is destroyed.

Returns:

constant reference to shared pointer object of U plane

Blob::Ptr& v()

Returns a reference to shared pointer to V plane.

Please note that reference to Blob::Ptr is returned. I.e. the reference will be valid until the I420Blob object is destroyed.

Returns:

reference to shared pointer object of V plane

const Blob::Ptr& v() const

Returns a constant reference to shared pointer to V plane.

Please note that reference to Blob::Ptr is returned. I.e. the reference will be valid until the I420Blob object is destroyed.

Returns:

constant reference to shared pointer object of V plane

virtual Blob::Ptr createROI(const ROI& roi) const

Creates a blob describing given ROI object based on the current blob with memory sharing.

Note: default implementation throws “not implemented” exception.

Parameters:

roi

A ROI object inside of the current blob.

Returns:

A shared pointer to the newly created ROI blob.
