プライバシーポリシー - 証明写真アプリ

# A. Data.

The photos used in this application are cropped to the size of a picture of the user's picture, and the user's Don't worry, it's not stored on our server as we only let you save them in your photo folder. It is only stored on the client side of the app, not on the server at all. They are only stored on the client side of the app and are not stored on the server at all. In other words, deleting the app will delete all the photos in the app.

# B. Face Control Function

We're not going to take a photo that was taken with a smartphone and use it elsewhere for proof photos. None. These data will not be misused by third parties and are protected by very appropriate measures. The images can only be viewed from the user's device. Since the images can only be viewed from the user's device, we will be able to send those data to you. We will not collect, disclose, share or retain it. When you delete the app, your data is immediately deleted.

# A. データについて

このアプリケーションにて利用される顔写真証明写真の大きさに切り取った後、ユーザー様の写真フォルダに保存させるだけなので、弊社のサーバーには保存されませんのでご安心ください。アプリクライアントサイドで保存されるだけで一切サーバーには保存されません。つまりアプリを削除することでアプリ内の写真はすべて削除されます

# B. 顔写真を撮ることについて

我々は、証明写真用に利用する写真スマホ撮影された写真を、それを他で活用することは一切ありません。これらのデータ第三者によって不正利用されたりしませんし、非常に適切な処置で守られていますユーザーの端末からし画像は閲覧できないようにしているので、弊社の方でそれらのデータ収集、開示、共有、保持することはありません。アプリを消していただくと直ちにデータが削除されるので、安心してお使いできます

Automatic classification of trees using a UAV onboard camera and deep learning

https://arxiv.org/abs/1804.10390

やったこ

Ecologyの研究には、情報科学世界研究されている画像解析の技術を使えば解決可能ものがある。著者らは、この一つである植物分布の計測を試みている。具体的な解決方法は、UAVデータから撮影した画像データを元に、木々の種類を識別する分類器を作成である。手順として、最初に、UAVから画像と高度データを著者自らが撮影を行った。次にそのデータから学習用の教師データをいくつかの手順を踏んで作成する。この手順は、さらなる研究を行う際にも適用可能である。結果、識別器は良い識別性能をだしている(Model1で83.1%)。前処理として、画像を切り分けて分類器にかけなければならないという点は未解決である

Identifying 3 moss species by deep learning, using the “chopped picture” method

https://arxiv.org/abs/1708.01986

何をしているのか。

著者らは、コケ植物画像判定を行うため、撮影した画像データから学習データ作成し、識別機を作っています

データは著者らが作成しており、少数の画像から判定機を作成するために、"chopped picture" methodを提案しています

この方法では、撮影画像から画像を切り分け、少部分にします。

画像枚数を多くするために、少部分間には50%のoverlapが存在します。言い換えるなら、ある画像は、他2枚の画像を元に再構築可能です。

CNN学習では、切り出した画像から、validation dataとtraining dataに分けて学習を行っています

以上の方法で、validation dataによってこの識別機の精度の計測をし、高い精度で識別できていることを主張している。

質問

提案手法は、training dataとvalidation dataに関係があるので、validation dataでの精度は高くなると思われます

言い換えると、全データ識別機がオーバーfittingしているので、validation dataでの精度が高くなっているのでは?

つぎに、この論文提案手法でのvalidation dataを識別機に食わしたさいの分類精度は、その識別機の分類精度とは言えません。

validation data・training dataに含まれていないdataセットを作成し、その新たなdataセットでの学習機の精度を検証するべきだと思います

この論文でやったこと・感想

管理されなくなった竹が他の植物の生えた地域侵略していくことが問題となっている。

この問題対処するには、竹の移動を経時的に追うこと、または、侵略しているか判別することが求められる。

論文は、この問題解決するために、Deep learningを用いて衛星画像データを竹とそれ意外に識別を試みる。

画像Google Earthから取得し、著者らが3種類のTag付けを行った。このデータを元に学習を行った。 

結果、非常に精度の高い識別機が構成できたと主張している。

ただし、衛生画像撮影した時期によって、精度が著しく損なわれるので、現時点では経時変化を追跡する課題解決されていない。

質問

Introduction

竹林が徐々に他の植生の場所侵略している。この問題解決するために、まずどこに竹が生えているのかを識別するのがこの論文目的

この課題解決するためにGoogleEarthの画像は適切なのか?言い換えれば、課題に対するシステム必要要件記述されていない。


Methods
実験評価

この論文提示している問題は、植物侵略を判定する識別器をつくることである。故に、竹やぶと建物の境目になる部分が正しく識別されていることがこのシステム必要要件である(多くの範囲が正確に識別されることは目標ではない)。

  • 上の基準で判定率を計算するべきだろう。
  • Figure 7をみると、画像中央広場南側植物との境目(黒い部分)は正確に判定されているのだろうか。
  • 上述と同じ箇所で、黒い部分は竹でないならなんなのだろうか?GoogleEarthで見れば、何が写っているのかがわかるのか?
  • Figure 7の正解データが見たい。

Transferability among the models
  • 撮影日の天候などによって影響がでることを述べているが、そのような結果は論文掲載されていない。
    • 実際の画像がみたい。
  • 撮影時の状況により、精度が著しく減少することを認めるなら、植物侵略を計測するという今回の研究目的は、達成されていない。
    • このことを明記するべきではないか
