“…Letessier e Bérard [6] propõem um algoritmo para rastreamento dos dedos da mão baseado em segmentação por diferenciação da imagem (Image Differencing Segmentation) e filtros de rápida rejeição (Fast Rejection Filters). Eles utilizam critérios geométricos para caracterizar as pontas dos dedos e a partir de um filtro de forma (shape filtering) conseguem extrair a posição dos dedos.…”

“…Typical user-centric criteria against which an interactive system is evaluated include overall latency, reliability and autonomy [7]. Here, we shortly describe these criteria and how they constrain the architecture of vision systems.…”

“…This is the case in the PDS example [3], where the interactive surface itself is tracked by the service. (b) In the general case, it must negotiate with the client application the display of a calibration grid [7].…”

“…A lack of agreement between the user and the sensing system on what is being tracked further limits resolution and can be the source of breakdowns in interaction. A number of related works pursue finger tracking approaches to recover absolute finger position [25], [21], [15], [19]. Another approach is to design a handheld prop which is tracked unambiguously [7], [4].…”
