0. Flask Rest API - in SunnyWeb : 이미지 변환 웹의 Flask Rest API

1. 구성

    1. flaskRestAPI01 : 이미지 변환 기능 중 유명 화가풍으로 변환, 안경과 동물들의 특징을 이미지에 추가하는 기능을 담당하는 flask Rest API
  • a) imgs : 안경, 돼지(코), 쥐(코, 귀) 이미지
  • b) models
    • b-1) instance_norm
    • b-2) eccv16
  • c) api_test01.py : json으로 request를 주었을 때를 테스트하는 모듈
  • d) app01.py : flask로 웹 서버를 올려 json request를 json response를 보내주는 flask Rest API
  • e) img_download.py : s3에서 이미지를 다운 받아서 임시 저장소에 이미지를 저장하는 함수를 가진 모듈
  • f) plusimage.py : 이미지와 파일 이름을 넣으면 이미지를 추가해주는 함수를 가진 모듈
  • g) total_pram : Rest API를 쉽게 사용할 수 있도록 조절할 파라미터만 모아 놓은 모듈
  • h) transiamge : 이미지와 파일 이름을 넣으면 이미지를 변환해주는 함수를 가진 모듈
  • i) upload_image : AWS S3의 버켓에 이미지를 업로드 하는 함수를 가진 모듈
  1. flaskRestAPI01 : 이미지 변환 기능 중 저화질의 이미지를 초고화질로 바꿔주는 기능을 담당하는 flask Rest API
a) api_test02.py : json으로 request를 주었을 때를 테스트하는 모듈
b) app02.py : flask로 웹 서버를 올려 json request를 json response를 보내주는 flask Rest API
c) img_download.py : s3에서 이미지를 다운 받아서 임시 저장소에 이미지를 저장하는 함수를 가진 모듈
d) total_pram : Rest API를 쉽게 사용할 수 있도록 조절할 파라미터만 모아 놓은 모듈
e) upload_image : AWS S3의 버켓에 이미지를 업로드 하는 함수를 가진 모듈 

2. 핵심 기능 및 파라미터 설명

  1. app01.py, app02.py

a) route /transimage : 이미지를 유명 화가풍으로 변환해주는 app

image

b) route /plussimage : 이미지에 쥐(코, 귀)의 이미지를 추가해주는 app

image

c) route /esrganimage : 저화질의 이미지를 초고화질의 이미지로 변환해주는 app

1. 라이브러리

  1. flask
  2. boto3
  3. openCV
  4. numpy
  5. dlib
  6. tansorflow

2. Rest API 조절 파라미터

  1. download_url = "다운로드 받을 url"
  2. s3_upload_bucket_name = "s3에 업로드할 버켓 이름"
  3. trans_image_model = "변환할 모델"
  • 변환 가능한 모델 리스트 : composition_vii.t7, la_muse.t7, starry_night.t7, the_wave.t7,

candy.t7, feathers.t7, la_muse.t7, mosaic.t7, starry_night.t7, the_scream.t7, udnie.t7

3. 프로세스 및 예시

  1. json으로 이미지 파일의 이름을 보낸다.

json1

  1. json으로 받은 이미지의 이름으로 s3에서 찾아 임시저장소에 다운로드한다.

업로드된원본

  1. 임시 저장한 이미지를 변환한 후에 이미지를 잠시 로컬에 저장한다.
  2. 변환된 이미지를 s3에 업로드한다.

변환된이미지업로드

  1. 업로드 후 변환된 이미지를 삭제한다.
  2. 변환된 이미지의 이름을 json으로 보낸다.

json2

결과

변환전후
