MLA and MJA Anthropometric angular measurements on the foot

<strong>DATASET DESCRIPTION </strong> These datasets contain a collection of dynamic measurements of the Medial Longitudinal Arch (MLA) angle and the Metatarsophalangeal Joint Angle (MJA), as well as coordinates of the centroid pixel of the landmarks placed on anthropometric points of the foot. The measurements are performed using the proposed system and Kinovea software during the cycle gait in eight subjects with an average age of 33 years and size foot of 8 inches. The dataset "Anthropometric Vision System" contains 950 measurements using the proposed system based on the dot product method and landmark detection algorithm, while the dataset "Kinovea" has 950 measurements using the Kinovea software. In addition, the videos Subject1.mp4 to Subject8.mp4 are utilized to generate datasets through the Anthropometric Vision System and Kinovea software. The columns of the 'Anthropometric Vision System' and 'Kinovea' datasets are derived from these videos. <br> A demonstration of the anthropometric angular measurements using both systems is shown in <br> the following videos. <strong>Anthropometric Vision System</strong><br> https://youtu.be/_lazLNw-LVE <strong>Kinovea</strong><br> https://youtu.be/_uA2wSwUz_8 <strong>COLUMNS ACRONYMS</strong> Subject: Subjects 1 - 8<br> MJA: Metatarsophalangeal Joint Angle (degrees)<br> MLA: Medial Longitudinal Arch (degrees)<br> L1X: X Coordinates of the centroid pixel for the landmark positioned on the proximal interphalangeal joint<br> L1Y: Y Coordinates of the centroid pixel for the landmark positioned on the proximal interphalangeal joint<br> L2X: X Coordinates of the centroid pixel for the landmark positioned on the sesamoid<br> L2Y: Y Coordinates of the centroid pixel for the landmark positioned on the sesamoid<br> L3X: X Coordinates of the centroid pixel for the landmark positioned on the navicular tuberosity<br> L3Y: Y Coordinates of the centroid pixel for the landmark positioned on the navicular tuberosity<br> L4X: X Coordinates of the centroid pixel for the landmark positioned on the posterior calcaneus<br> L4Y: Y Coordinates of the centroid pixel for the landmark positioned on the posterior calcaneus**数据集说明** 本数据集集合了足内侧纵弓（Medial Longitudinal Arch, MLA）角度与跖趾关节（Metatarsophalangeal Joint Angle, MJA）的动态测量数据，以及附着于足部人体测量学点位的标记点质心像素坐标。 本次测量针对8名平均年龄33岁、鞋码8英寸的受试者，在其步态周期中分别采用自研系统与Kinovea软件完成数据采集。 名为「人体测量视觉系统（Anthropometric Vision System）」的数据集包含950组基于点积法与标记点检测算法的自研系统测量数据，而「Kinovea」数据集则包含950组通过Kinovea软件采集的测量数据。 此外，本次数据集依托Subject1.mp4至Subject8.mp4共8段视频生成，上述两个数据集的字段均源自这些视频素材。 两种系统的人体测量学角度测量演示视频如下： **人体测量视觉系统**：https://youtu.be/_lazLNw-LVE **Kinovea**：https://youtu.be/_uA2wSwUz_8 **字段缩写说明** - 「Subject」：受试者1至8 - 「MJA」：跖趾关节角度（单位：度） - 「MLA」：足内侧纵弓角度（单位：度） - 「L1X」：近节指间关节处标记点的质心像素X坐标 - 「L1Y」：近节指间关节处标记点的质心像素Y坐标 - 「L2X」：籽骨处标记点的质心像素X坐标 - 「L2Y」：籽骨处标记点的质心像素Y坐标 - 「L3X」：舟骨粗隆处标记点的质心像素X坐标 - 「L3Y」：舟骨粗隆处标记点的质心像素Y坐标 - 「L4X」：后跟骨处标记点的质心像素X坐标 - 「L4Y」：后跟骨处标记点的质心像素Y坐标
