# IntermediateResultUnit

The `IntermediateResultUnit` class represents an intermediate result unit used in image processing. It is an abstract base class with multiple subclasses, each representing a different type of unit such as pre-detected regions, localized barcodes, decoded barcodes, localized text lines, binary image, gray image, etc.

## Definition

*Module:* core

```python
class IntermediateResultUnit 
```

| [`get_original_image_tag`](#get_original_image_tag) | Gets the image tag of the original image. |
| [`get_transform_matrix`](#get_transform_matrix) | Gets the transformation matrix based on [`EnumTransformMatrixType`]({{ site.dcvb_python_api }}core/enum-transform-matrix-type.html). |
| [`get_type`](#get_type) | Gets the type of the intermediate result unit. |
| [`get_usage_count`](#get_usage_count) | Gets the usage count of the intermediate result. |
| [`clone`](#clone) | Creates a copy of the intermediate result unit. |
| [`replace`](#replace) | Replaces the `IntermediateResultUnit` object to the specified `IntermediateResultUnit` object. |
