 # Mixed image data augmentation update
 
-Mixed image data augmentation is similar to Mosaic and MixUp, in which the annotation information of multiple images needs to be fused during the runtime. In the OpenMMLab data augmentation pipeline, the other indexes of the dataset are generally not available. In order to achieve the above function, in the [MultiImageMixDataset](https://github.com/open-mmlab/mmdetection/blob/master/mmdet/datasets/dataset_wrappers.py#L338) the concept of dataset wrapper is proposed in YOLOX, which is reproduced in MMDetection.

MMYOLO has the following advantages over the original implementation:
 
-1. MMDetection in the `bbox_head` split into `assigner` + `box coder` + `sampler` three large components, but for the generality of passing through the 3 components , the model need to encapsulate additional objects to handle, and after the unification, the user needn't separate them. The benefits of not deliberately forcing the division of the three components are: no longer need to data encapsulation of internal data, simplifying the code logic, reducing the difficulty of use and the difficulty of algorithm implementation.
-2. MMYOLO is Faster, the user can customize the implementation of the algorithm when the original framework does not depend on the deep optimization of part of the code.
+1. In MMDetection, `bbox_head` is split into three large components: `assigner` + `box coder` + `sampler`. But because the transfer between these three components is universal, it is necessary to encapsulate additional objects. With the unification in MMYOLO, users do not need to separate them. The advantages of not deliberately forcing the division of the three components are: data encapsulation of internal data is no longer required, code logic is simplified, and the difficulty of community use and algorithm reproduction is reduced.
+2. MMYOLO is Faster. When users customize the implementation algorithm, they can deeply optimize part of the code without relying on the original framework.
 
-In general, in the MMYOLO, they only need to implement the decouple of the model + `loss_by_feat` parts, and users can achieve any model with any `loss_by_feat` calculation process through modify the configuration. For example, applying the YOLOX `loss_by_feat` to the YOLOv5 model, etc.
