Abstract: There is provided a battery module capable of enhancing insulation property and safety. The battery module includes two or more battery cells arranged in one direction, and each having a vent; a housing that accommodates the battery cells and has a top cover; and a sub cover that is provided to cover at least one portion of tops of the battery cells, and allows the battery cells and the top cover to be spaced apart from each other.

Abstract: A method for classifying a plant leaf by utilizing the feature points of venation has been developed. A sample image of the venation can be extracted by utilizing a Curvature Scale Space (CSS) Corner Detection Algorithm. The sample image is treated to thicken the venation and increase the contrast through the retrieval unit prior to applying the Canny Edge Detection technology. The feature point, Branching Point and End Point is detected at each point where the calculated curvature angle is a local maximum. The distribution of the feature points of the extracted venation is calculated by applying a Parzen Window non-parametric estimation method.
