Approximated Slack Scaling for Structural Support Vector Machines in Scene Depth Analysis
Figure 6
(a) the effect of the edge features. 1 to 7 means 1000, 0100, 0010, 1100, 1010, 0110, 1110. It shows that the edge features can boost the accuracy. (b) the effect of the RGB features. 1 to 7 means 0100, 0010, 0001, 0110, 0101, 0011, 0111. It shows that the RGB features can reduce the accuracy and the color feature with the texture features that can boost the inference accuracy. (c) the effect of the YCbCr features. 1 to 7 means 1000, 0010, 0001, 1010, 1001, 0011, 1011. It is easy to find that the YCbCr features have a similar effect on the accuracy with the RGB features. (d) the effect of the Laws’ masks scaled 3 × 3. 1 to 7 means 1000, 0100, 0001, 1100, 1001, 0101, 1101. It is easy to find that the texture features can boost the accuracy in most of the situations.
