wmc_e6 2018.10.21 | more works by Hector Rodriguez from his solo “Hidden Variables”: (2014-2016; 2018) | 羅海德作品繼續介紹:《Z》(2018版)

Z is a moving image analysis system that produces abstract representations of video sequences using a system of predefined grayscale disks, thus facilitating the critical understanding and aesthetic appreciation of cinematic rhythm.

Each disk responds to different aspects of the brightness of each frame. Changes in the higher frequencies reflect changes in the smaller details of the source image. Changes in the lower frequencies reflect changes in the overall shape of the source image.

Z employs a mathematical framework originally devised by physicist Frits Zernike to describe the aberrations of microscopes, telescopes and other optical systems.

Kurosawa’s Throne of Blood (1957) deconstructed analytically by Rodriguez’s self-authored software “Z

In the WMC_e6 exhibition, two source films, of varied motion and brightness contrast, are used to heighten the visitor’s study of the power of the software. On one wall is Bela Tarr’s The Man from London (2007) and, on the opposite wall, Akira Kurosawa’s Throne of Blood (1957).

《Z》是一個透過預設的灰階圓盤組合的抽象影像的分析系統,背後概念來自物理學家弗里茨・塞爾尼克用於計較算光學像差(如顯微鏡誤差)的研究。程式將每幀影格不同光暗層級呈現於不同的灰階圓盤內,複雜的圓盤圖像用於分析電影的影像細節,相反單格的圓盤圖像則用於分析電影的整體結構。

 

The visual interface of Z as an analytical tool and display of changing brightness and amount of visual information within each frame… The symmetrical structure represents the complex numbers involved in the calculation. Discs at the bottom line add up vertically to the discs on top. Horizontally, the discs at top of the screen add up from outside towards the centre into 2 images, which then combine to form the single disc in the lower centre, which is the closest approximation of the film’s original image.
