In order to improve its performance,this paper proposes bicubic convolution template algorithm:make the bicubic interpolation discrete and infer 16 templates,in which the original real operations are replaced by integer operations.

Considering the problems existing in prefecture-level TV weather forecast program making,with the VB programming tool and the reflectivity factor data from new-gerenration radar,a TGA document series with an Alpha channel is generated,by means of the cubic convolution interpolation algorithm scaling.

Draw lessons from the filtering based on template convolution in digital image processing,a new method of outlier elimination is proposed.

According to the correlation of measurement data,combining with the theory of least square,a new method of outlier elimination is proposed by improving the principle of template convolution method which we proposed sometimes ago.

This paper presents the scheme for designing the 2-D convolution mask of Gabor filter in the frequency domain, This scheme avoids the problem of choosing the sampling frequency in the spatial domain, or the sampling frequency must be determined when the mask is obtained by means of sampling the Gabor function, the impulse response of the Gabor filter.

To improve the arithmetic operation speed,it constructed the two type LS-SVR convolution mask based on the filtering strategy and LS-SVR characteristic,training process of LS-SVR is turned into simple weighted summation operation which increased the algorithmic practicability.

Custom convolution template is used to locate no-close eye.
