چکیده

An overlooked, yet essential problem in piano practice involves body posture. Bending the back, leaning towards the keys, lifting the wrist and other improper positions are usually noticed by piano teachers when instructing their students. If they sit too low, fingers will feel the burden of static arm weight; if they sit too high, the playing might become rigid with tension in wrist and shoulders. In this manner, visual feedback can help in realizing potential problems when playing the instrument. This paper discusses an innovative application of the techniques used for the 3D visualization of piano performances in any possible view, with the purpose of comparing them to a good model of someone playing the piano. It includes the capture and reconstruction of the 3D motion and posture of a professional piano player so that it may be compared against the posture and movements of students, by overlaying 2D videos of their practice session at the piano.

Comparing the Behavior Hydrodynamics Flow Over of Type A, B, and C Piano Key Weirs

The piano key weir (PKW) is a new type of hydraulic structure that has been of great interest to designers in recent years. In the present study, steady flow on the types A, B, and C PKWs was studied numerically using the FLOW-3D numerical model. Upon software validation using the experimental data, the 3D flow pattern on the types A, B, and C PKWs was studied, and along with the evaluation of ...

Video Subject Inpainting: A Posture-Based Method

Despite recent advances in video inpainting techniques, reconstructing large missing regions of a moving subject while its scale changes remains an elusive goal. In this paper, we have introduced a scale-change invariant method for large missing regions to tackle this problem. Using this framework, first the moving foreground is separated from the background and its scale is equalized. Then, a ...

A laboratory investigation on the potential of computational intelligence approaches to estimate the discharge coefficient of piano key weir

The piano key weir (PKW) is a type of nonlinear control structure that can be used to increase unit discharge over linear overflow weir geometries, particularly when the weir footprint area is restricted To predict the outflow passing over a piano key weir, the discharge coefficient in the general equation of weir needs to be known. This paper presents the results of laboratory model testing of...
