Fluxions [1], Lambda print on metallic paper, 120 x 73 cmFluxions is an image processing system that visualizes video sequences as changing configurations of pixels. It segments the original video into short clips and applies a motion tracking algorithm to produce a vector description of their movement. It stores the first image of each clip as a key frame, and gradually shifts the values of its pixels based on the vector descriptions of the subsequent frames.
The result can be seen as an abstract visualization of the variation in the original movie. Viewers can also try to recognize or infer the missing objects and events. This tension between figuration and abstraction, between presence and absence, is the heart of this project.
On site at “Hidden Variables,” the artists showed us three metallic prints and one video.
Fluxions [6], Lambda print on metallic paper, 120 x 73 cm, based onThe Rape of the Vampire (1966) by Jean RollinFluxions [2], Lambda print on metallic paper, 120 x 73 cm《流數》(Fluxions) 是個處理影像的系統,把本來的錄像片段呈現為像素的重複組合。程式把原有的錄像切割成小段,以動態捕捉技術分析電影選段畫面,從而生成出影像動態的向量表,其後以選段的第一幀畫面作為關鍵影格,跟據計算出的向量表而逐漸改變像素數值以構成下一幀影格。影像除了是電影的抽象變奏外,觀眾亦可嘗試辨別畫中沒被顯現的物件與情節。因此《流數》經常處於抽象與具體之間,存在與不存在之間,而這正是作品的核心。
