STEP 8: Instantiate/create your object Classes are the blueprints/templates of php objects. Classes don't actually become objects until you do something called: instantiation. When you instantiate a class, you create an instance of it, thus creating the object. In other words, instantiation is the process of creating an instance of an object in

3.1 Object detection set prediction loss DETR infers a xed-size set of N predictions, in a single pass through the decoder, where N is set to be signi cantly larger than the typical number of objects in an image. One of the main di culties of training is to score predicted objects (class, position, size) with respect to the ground truth.

• An object has structural properties defined by a finite set of attributes and behavioural properties defined by a finite set of methods. • Each object is associated with a logical non-reusable and unique object identifier (OID). The OID of an object is independent of the values of its attributes.

object, but without any actual existence. An object is a particular instance of a class which has actual existence and there can be many objects (or instances) for a class. Static variables and methods are not purely object oriented because they are not specific to instances (objects) but common to all instances.

ImageNet demonstrate that DetCo not only outperforms re-cent methods on a series of 2D and 3D instance-level de-tection tasks, but also competitive on image classification. For example, on ImageNet classification, DetCo is 6.9% and 5.0% top-1 accuracy better than InsLoc and DenseCL, which are two contemporary works designed for object de-tection.

Thus, object is an instance of a class. The constituents of a class are: A set of attributes for the objects that are to be instantiated from the class. Generally, different objects of a class have some difference in the values of the attributes. Attributes are often referred as class data.
