はじめに こんにちは、AIシステム部でコンピュータビジョンの研究開発をしている加藤です。我々のチームでは、常に最新のコンピュータビジョンに関する論文調査を行い、部内で共有・議論しています。今回は 2D Human Pose Estimation 編として加藤直樹 ( @nk35jk ) が調査を行いました。 本記事では 2D Human Pose Estimation に関する代表的な研究事例を紹介するとともに、2019年10月から11月にかけて開催されたコンピュータビジョンのトップカンファレンスである ICCV 2019 に採録された 2D Human Pose Estimation の最新論文を紹介します。 過去の他タスク編については以下をご参照ください。 Human Recognition 編 (2019/04/26) 3D Vision 編 (2019/06/04) キーポイント検
QMULのBen Hayes氏らが、勾配降下法で周波数推定を行う手法を論文で発表しました。ICASSP2023に投稿したそうです。 きわめてシンプルな手法なのですが、機械学習系音声合成にとってはたいへん重要な成果だと思うので、紹介します。 論文リンク:Sinusoidal Frequency Estimation by Gradient Descent ソースコード:https://github.com/ben-hayes/sinusoidal-gradient-descent 背景:DDSPの限界 DDSP(Differentiable Digital Signal Processing)とは、微分可能な計算式を持つDSPモジュールをDNNに組み込んで機械学習をやる手法で、Google Magentaプロジェクトが最初に打ち出したアイデアです。 今ではもうDDSPシリーズと呼べるほど多様
January 22, 2020 When I first joined Netlify over 2 years ago, I took over sprint planning for a while. As many teams do, they were doing a sort of scrum-lite. They didn’t have an estimation scale and we all agreed at various times that the traditional scrum scales of t-shirt sizes or fun bucks didn’t really capture the concept of scoring complexity. So, I came up with a scale I thought captured c
Abstract We present an algorithm for reconstructing dense, geometrically consistent depth for all pixels in a monocular video. We leverage a conventional structure-from-motion reconstruction to establish geometric constraints on pixels in the video. Unlike the ad-hoc priors in classical reconstruction, we use a learning-based prior, i.e., a convolutional neural network trained for single-image dep
Estimation of total and excess mortality due to COVID-19 Published October 15, 2021 This page was updated on October 15, 2021 to reflect changes in our modeling strategy. View our previous methods published May 13, 2021 here. In our October 15 release, we introduced three major changes. First, we have very substantially updated the data and methods used to estimate excess mortality related to the
Jetson NanoでPose Estimation Jetson Nanoで骨格検出の技術を動かしてみます。「tf-pose-estimation」というソフトを使うと単眼カメラで人間の骨格検出をすることができます。詳しくは以下ブログ記事を参照下さい。 単眼カメラでKinectのように骨格検出する技術「Realtime Multi-Person Pose Estimation」を試してみた Jetson Nanoで「tf-pose-estimation」のセットアップ ほとんど以下の記事を参考にさせていただきました。おかげで詰まることなくセットアップできたので、本当に感謝です。 Jetson Nano に TensorFlow版のOpenpose入れてみる そのままだと付加価値がないので、上記のセットアップをコマンド一発で実行できるようにスクリプトにした上で、Raspberry Piカ
We propose a method that can generate highly detailed high-resolution depth estimations from a single image. Our method is based on optimizing the performance of a pre-trained network by merging estimations in different resolutions and different patches to generate a high-resolution estimate. Abstract Neural networks have shown great abilities in estimating depth from a single image. However, the
To overcome the computational bottleneck of various data perturbation procedures such as the bootstrap and cross validations, we propose the Generative Multiple-purpose Sampler (GMS), which constructs a generator function to produce solutions of weighted M-estimators from a set of given weights and tuning parameters. The GMS is implemented by a single optimization without having to repeatedly eval
Estimating Software Projects: Software Estimation Is Hard. Do It Anyway.It’s well-established that estimating software projects is hard. One study by HBR found that one in six IT projects had cost overruns of over 200% and were late by almost 70%. Another study by McKinsey found that IT projects are on average 45% over budget and 7% over schedule. They found large software projects were particular

Effort estimation is an important component of any project, software or otherwise. While effort estimation is something that everybody in industry is involved with on a regular basis, it is a niche topic in software engineering research. The problem is researcher attitude (e.g., they are unwilling to venture into the wilds of industry), which has stopped them acquiring the estimation data needed t

Every Information Technology (IT) project has direct and indirect cost implications. Therefore, an effective and practical estimation of any information technology project is crucial. As evident from the name, the direct cost is the money invested in executing the project. However, the impact of the indirect costs can also be substantial for a software project. Regardless, while the accurate estim
