Sentence examples for directions filter from inspiring English sources

Conventional feature selection approaches can be divided into three main directions: filter, wrapper, and embedded methods [57].

G i,j) is the output of this filtering for each pixel (i,j) in the input image I. Gabor filters can best be thought of as a direction filter that when the orientation of the gabor filter is perpendicular to that of the ridge orientation the image is enhanced along that direction.

This is achieved by proposed edge detection method which involves two steps: (1) a 2D-direction filter is designed accordingly to enhance the contrast between the background and the scratches then (2) a modified adaptive threshold method is employed to automatically detect the edge of the scratches on a filtered image.

L = length in flow direction (filter thickness) (m).

To achieve the direction filter of the high frequency coefficients after decomposition of f d j n 1, n 2, we should construct a shear direction filter using window function.

In Fig. 11 (left), despite being removed due to the amplitude and gradient direction filter, the ship target radial edge does not affect the detection results.

First module is detection of road network using different morphological direction filter, and second module is extraction of road intersection to determine road orientation.

In this paper, the Laplacian pyramid followed by the direction filter banks decomposition in the contourlet transform using the two filter banks above and the image denoising applications in the contourlet hidden Markov tree model are implemented, respectively.

However, Gabor exhibited an apparent decrease in CVA of 25.92%, which we tentatively attribute to the use of only one direction filter for all head-orientation images; this will be confirmed in future research.

In Figure 4, vertical line D is cross some croplands and forms these show comb structure in Figure 5. Figures 4(b), 4(c), 4(d), 4 e), 4(f), and 4(g) demonstrate that the above traditional filters cannot preserve the narrow strips perfectly due to only inhibiting smoothing near edges and not supporting direction filter.

Method I: Only Direction Filter applied.
