Method for automatic extrapolation of designs across apparel and accessory sizes and types
A method for modifying the dimensions of a design pattern embedded on a garment is disclosed. Original dimensions of the apparel and new dimensions according to which the apparel is to be modified are determined. A coordinate pair indicating the center point of the design pattern is determined. Two delta factors, one corresponding to height and the other corresponding to the width are determined. The delta factors indicate the difference, in terms of height and width respectively, between the original dimensions of the garment, and the dimensions to which the garment is purported to be modified. Subsequently, one of the delta factors is selected depending upon the nature of modification, and provided as an input to an affine transformation operation, along with the coordinate pair. The dimensions of the design pattern are modified based on the affine transformation operation and the selected delta factor and coordinate pair.
1. A computer implemented method for modifying dimensions of a garment having at least one design pattern embedded thereupon, said method comprising the following computer implemented steps:
determining original height and original width of the garment;
determining a second height and a second width, said second height and second width indicative of a modified dimension of the garment;
determining a coordinate pair indicative of a center point of the design pattern embedded on the garment;
calculating a first delta factor, said first delta factor being a value corresponding to a difference between the original width and the second width;
calculating a second delta factor, said second delta factor being a value corresponding to a difference between the original height and the second height;
determining a maximum value and a minimum value based on a comparison of the value of said first delta factor with the value of said second delta factor;
applying an affine transformation operation on the original height and original width of the garment, and providing said coordinate pair and at least one of said maximum value and said minimum value as inputs to said affine transformation operation; and
modifying the original height and original width of the garment in accordance with at least one of said maximum value and minimum value, and selectively adjusting said coordinate pair on modified height and modified width of the garment, using said affine transformation operation.
2. The method as claimed in claim 1 , wherein the step of modifying the original height and original width of the garment further includes the step of selectively extrapolating the original height and original width of the garment using said affine transformation operation, and in accordance with said maximum value.
3. The method as claimed in claim 1 , wherein the step of modifying the original height and original width of the garment further includes the step of selectively reducing the original height and original width of the garment using said affine transformation operation, and in accordance with said minimum value.
