Overview

SAHI: Slicing Aided Hyper Inference

A vision library for performing sliced inference on large images/small objects

Overview

Object detection and instance segmentation are by far the most important fields of applications in Computer Vision. However, detection of small objects and inference on large images are still major issues in practical usage. Here comes the SAHI to help developers overcome these real-world problems.

Getting started

Blogpost

Check the official SAHI blog post.

Installation

Install sahi using conda:

conda install -c obss sahi

Install sahi using pip:

pip install sahi

Install your desired version of pytorch and torchvision:

pip install torch torchvision

Install your desired detection framework (such as mmdet):

pip install mmdet

Usage

Sliced inference:

result = get_sliced_prediction(
    image,
    detection_model,
    slice_height = 256,
    slice_width = 256,
    overlap_height_ratio = 0.2,
    overlap_width_ratio = 0.2
)

Refer to inference notebook for detailed usage.

Slice an image:

from sahi.slicing import slice_image

slice_image_result, num_total_invalid_segmentation = slice_image(
    image=image_path,
    output_file_name=output_file_name,
    output_dir=output_dir,
    slice_height=256,
    slice_width=256,
    overlap_height_ratio=0.2,
    overlap_width_ratio=0.2,
)

Slice a coco formatted dataset:

from sahi.slicing import slice_coco

coco_dict, coco_path = slice_coco(
    coco_annotation_file_path=coco_annotation_file_path,
    image_dir=image_dir,
    slice_height=256,
    slice_width=256,
    overlap_height_ratio=0.2,
    overlap_width_ratio=0.2,
)

Adding new detection framework support

sahi library currently only supports MMDetection models. However it is easy to add new frameworks.

All you need to do is, creating a new class in model.py that implements DetectionModel class. You can take the MMDetection wrapper as a reference.

add support for video prediction
This PR brings full support for sliced/standard inference for video input format for all MMDetection/Detectron2/YOLOv5 models :fire:

Just give video file as source:

sahi predict --model_path yolov5s.pt --model_type yolov5 --source video.mp4 --export_visual

You can also view video render during video inference with --view_video:

sahi predict --model_path yolov5s.pt --model_type yolov5 --source video.mp4 --export_visual --view_video

To forward 100 frames, on opened window press key D

To revert 100 frames, on opened window press key A

To forward 20 frames, on opened window press key G

To revert 20 frames, on opened window press key F

To exit, on opened window press key Esc

Note: If --view_video is slow, you can add --frame_skip_interval=20 argument to skip interval of 20 frames each time.

Added support for exporting predictions in COCO format

changelog: -

COCO prediction object of class CocoPrediction can be added into COCO image object of class sahi.utils.cocoCocoImage using method <CocoImage_Instance>.add_prediction
__repr__ method updated to reflect predictions in class sahi.utils..coco.CocoImage
Additional property prediction_array added in class sahi.utils.coco.Coco to export COCO predictions in json-serializable format. Logic for the property is defined in new function sahi.utils.coco.create_coco_prediction_array
added the test cases for the same in test_cocoutils.py
updated file coco.md with necessary documentation

Basic flow is like this

from sahi.utils.coco import Coco, CocoImage, CocoAnnotation, CocoPrediction
from sahi.utils.file import save_json

coco_obj = Coco()

# add n images to coco_obj
for _ in range(n):
    image = CocoImage(**kwargs)
    
    # add n annotations to the image
    for _ in ange(n):
        image.add_annotation(CocoAnnotation(**kwargs))
    
    # add n predictions to the image
    for _ in range(n)
        image.add_prediction(CocoPrediction(**kwargs))
    
    # add image to coco object
    coco_obj.add_image(image)

# export ground truth annotations
coco_gt = coco_obj.json
save_json(coco_gt , "ground_truth.json")

# export preadictions 
coco_predictions = coco_obj.prediction_array
save_json(coco_predictions, "predictions.json"

Why this is useful?

The user can utilize the exported files to calculate standard coco metrics using offical COCO api pycocotool with relative ease. This is example of using that

from pycocotools.cocoeval import COCOeval
from pycocotools.coco import COCO

# load json files
coco_ground_truth = COCO(annotation_file="ground_truth.json")
coco_predictions = coco_ground_truth.loadRes("predictions.json")

coco_evaluator = COCOeval(coco_ground_truth, coco_predictions, "bbox")
coco_evaluator.evaluate()
coco_evaluator.accumulate()
coco_evaluator.summarize()

This can be further expanded to define class which can be conveniently used to evaluate the prediction, something like this

class DatasetEvalutor:
    # user can inherit and overwrite the given load_model, get_annotation and get_prediction methods
    def __init__(self, **kwargs):
        self.images = []  # list of image meta data
        self.model = None # model place holder
        self.dataset = Coco() # coco object

    def load_model(self,**kwargs):
        # logic for loading model goes here
        # set self.model to model

    def get_annotation(self, **kwargs):
        # logic for annotation goes here
        # result must return a sahi.utils.coco.CocoAnnotation instance

    def get_prediction(self, **kwargs):
        # logic for prediction goes here
        # result must return a sahi.utils.coco.CocoPrediction instance

    def run_inference(self, **kwargs):
        # loop over images create CocoImage and add annotations and prediction to it
        # add those CocoImage instance into self.dataset

    def evaluate(self, **kwargs):
        # pycocotool code to generate metrics

Downgrade Pillow

Issue

When running the sahi colab notebooks, an error occurs when attempting to run inference using a pretrained model:

ImportError                               Traceback (most recent call last)
[<ipython-input-5-6c3be4aaa524>](https://localhost:8080/#) in <module>

ImportError: cannot import name 'is_directory' from 'PIL._util' (/usr/local/lib/python3.8/dist-packages/PIL/_util.py)

Solution

A solution to this problem (as per this stack overflow post) is to downgrade Pillow and freeze it at version 6.2.2. Using this version of Pillow allows users to successfully execute the entire notebook demonstrating the functionality of sahi.

Risks

Freezing the version of Pillow to an earlier state may result in unexpected behaviour, and lead to vulnerabilities in the future if more up to date versions of Pillow are not supported.

Changed Mask class to store RLE encoded masks to save RAM.

Changed Mask class to store RLE encoded masks to save RAM usage on large images. (Work in progress)

When doing inference on large images (5300, 3600) pixel with around 100 instances, the sahi library uses around 14 GB of RAM. I introduced internal conversion to RLE encoded masks in the Mask class to save RAM memory and got it down to around 2GB RAM usage for our use-case (see plots).

Since pycocotools are a bit tricky to install on windows, the code are designed to utilize RLE encoding if pycocotools are available.

The inference time does not seem to increase by these changes, but only ran a single test so take the results with a grain of salt.

add support to instantiate a `DetectionModel` from layer
This PR adds support to instantiate a DetectionModel out of a YOLOv5 model trained on Layer. It includes:

A new from_layer() method in AutoDetectionModel to load models from Layer.

A new set_model() method in DetectionModel to create a DetectionModel out of an already loaded model.

Tests for from_layer() and set_model().

Example

You can pass a path of a YOLOv5 model trained on Layer to instantiate a DetectionModel. Here we fetch the yolo5vs pretrained model from this Layer project

from sahi import AutoDetectionModel detection_model = AutoDetectionModel.from_layer("layer/yolov5/models/yolov5s")

Tests

To run the tests related to from_layer() functionality you can:

pytest tests/test_layer.py
