Corruption Invariant Learning for Re-identification

The official repository for Benchmarks for Corruption Invariant Person Re-identification (NeurIPS 2021 Track on Datasets and Benchmarks), with exhaustive study on corruption invariant learning in single- and cross-modality ReID datasets, including Market-1501-C, CUHK03-C, MSMT17-C, SYSU-MM01-C, RegDB-C.

The repo. of CIL for cross-modal ReID is HERE

Brief Introduction

When deploying person re-identification (ReID) model in safety-critical applications, it is pivotal to understanding the robustness of the model against a diverse array of image corruptions. However, current evaluations of person ReID only consider the performance on clean datasets and ignore images in various corrupted scenarios. In this work, we comprehensively establish 5 ReID benchmarks for learning corruption invariant representation.

Maintenance Plan

The benchmark will be maintained by the authors. We will get constant lectures about the new proposed ReID models and evaluate them under the CIL benchmark settings in time. Besides, we gladly take feedback to the CIL benchmark and welcome any contributions in terms of the new ReID models and corresponding evaluations. Please feel free to contact us, wangzq_2021@outlook.com .

TODO:

• other datasets configurations
• get started tutorial
• more detailed statistical evaluations
• checkpoints of the baseline models
• cross-modality preson Re-ID dataset, CUHK-PEDES
• vehicle ReID datasets, like VehicleID, VeRi-776, etc.

(Note: codebase from TransReID)

Evaluating Corruption Robustness On-the-fly

Corruption Transform

The main code of corruption transform. (See contextual code in ./datasets/make_dataloader.py, line 59)

from imagecorruptions.corruptions import *

corruption_function = [gaussian_noise, shot_noise, impulse_noise, defocus_blur,
    glass_blur, motion_blur, zoom_blur, snow, frost, fog, brightness, contrast,
    elastic_transform, pixelate, jpeg_compression, speckle_noise,
    gaussian_blur, spatter, saturate, rain]
    
class corruption_transform(object):
    def __init__(self, level=0, type='all'):
        self.level = level
        self.type = type

    def __call__(self, img):
        if self.level > 0 and self.level < 6:
            level_idx = self.level
        else:
            level_idx = random.choice(range(1, 6))
        if self.type == 'all':
            corrupt_func = random.choice(corruption_function)
        else:
            func_name_list = [f.__name__ for f in corruption_function]
            corrupt_idx = func_name_list.index(self.type)
            corrupt_func = corruption_function[corrupt_idx]
        c_img = corrupt_func(img.copy(), severity=level_idx)
        img = Image.fromarray(np.uint8(c_img))
        return img

Evaluating corruption robustness can be realized on-the-fly by modifing the transform function uesed in test dataloader. (See details in ./datasets/make_dataloader.py, Line 266)

val_with_corruption_transforms = T.Compose([
    corruption_transform(0),
    T.Resize(cfg.INPUT.SIZE_TEST),
    T.ToTensor(),])

Rain details

We introduce a rain corruption type, which is a common type of weather condition, but it is missed by the original corruption benchmark. (See details in ./datasets/make_dataloader.py, Line 27)

def rain(image, severity=1):
    if severity == 1:
        type = 'drizzle'
    elif severity == 2 or severity == 3:
        type = 'heavy'
    elif severity == 4 or severity == 5:
        type = 'torrential'
    blur_value = 2 + severity
    bright_value = -(0.05 + 0.05 * severity)
    rain = abm.Compose([
        abm.augmentations.transforms.RandomRain(rain_type=type, 
        blur_value=blur_value, brightness_coefficient=1, always_apply=True),
        abm.augmentations.transforms.RandomBrightness(limit=[bright_value, 
        bright_value], always_apply=True)])
    width, height = image.size
    if height <= 60:
        scale_factor = 65.0 / height
        new_size = (int(width * scale_factor), 65)
        image = image.resize(new_size)
    return rain(image=np.array(image))['image']
