+# TextNet
+
+## Overview
+
+The TextNet model was proposed in [FAST: Faster Arbitrarily-Shaped Text Detector with Minimalist Kernel Representation](https://arxiv.org/abs/2111.02394) by Zhe Chen, Jiahao Wang, Wenhai Wang, Guo Chen, Enze Xie, Ping Luo, Tong Lu. TextNet is a vision backbone useful for text detection tasks. It is the result of neural architecture search (NAS) on backbones with reward function as text detection task (to provide powerful features for text detection).

+    Args:
+        stem_kernel_size (`int`, *optional*, defaults to 3):

+            The stride for the initial convolution layer.
+        stem_num_channels (`int`, *optional*, defaults to 3):
+            The num of channels in input for the initial convolution layer.
+        stem_out_channels (`int`, *optional*, defaults to 64):

+        stem_act_func (`str`, *optional*, defaults to `"relu"`):
+            The activation function for the initial convolution layer.
+        image_size (`Tuple[int, int]`, *optional*, defaults to `[640, 640]`):
+            The size (resolution) of each image.
+        conv_layer_kernel_sizes (`List[List[List[int]]]`, *optional*):
+            A list of stage-wise kernel sizes. If `None`, defaults to:

+        hidden_sizes (`List[int]`, *optional*, defaults to `[64, 64, 128, 256, 512]`):
+            Dimensionality (hidden size) at each stage.
+        batch_norm_eps (`float`, *optional*, defaults to 1e-05):
+            The epsilon used by the batch normalization layers.
+        initializer_range (`float`, *optional*, defaults to 0.02):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+        out_features (`List[str]`, *optional*):
+            If used as backbone, list of features to output. Can be any of `"stem"`, `"stage1"`, `"stage2"`, etc.
+            (depending on how many stages the model has). If unset and `out_indices` is set, will default to the
