Finding The Finger By The Boundary Vector Product
نویسنده
چکیده
A finger finding procedure has been presented to recognize the finger number of the hand gesture. The hand gesture is extracted from the stationary background and transformed into a binary image. The hue attribute, that is, the I value in the YIQ color space is used to extract the hand gesture shape. This attribute is not so sensitive to the light change and the other noises while catching the image frames. The binary image of the hand gesture shape is processed with erosion several times to eliminate the noises and then processed with dilation several times to recover the original shape. After the removal of the image noises, a boundary detection algorithm is used to trace the border of the hand shape from the binary image. The border of the hand shape can be used to calculate the vector product along the boundary. From the vector product along the boundary, the finger number of the hand gesture can be obtained.

On the character space of vector-valued Lipschitz algebras
We show that the character space of the vector-valued Lipschitz algebra $Lip^{alpha}(X, E)$ of order $alpha$ is homeomorphic to the cartesian product $Xtimes M_E$ in the product topology, where $X$ is a compact metric space and $E$ is a unital commutative Banach algebra. We also characterize the form of each character on $Lip^{alpha}(X, E)$. By appealing to the injective tensor product, we the...
