WebJun 23, 2014 · Detection of scale-space extrema The scale-space theory is used to describe the multi-scale characteristic of one image. The Gaussian Convolution Kernel is the only linear kernel to achieve the scale transform; therefore, a 2D scale space is defined L(x,y,s)=G(x,y,s) I(x,y) ð1Þ where G(x,y,s) is the invariable scale Gaussian func- WebJun 1, 2016 · Figure 1: Scale-invariant interest points detected from a grey-level image using scale-space extrema of the Laplacian. The radii of the circles illustrate the selected detection scales of the interest points. Red circles indicate bright image features with , whereas blue circles indicate dark image features with .

For each one of the resulting 14× (1+10)=154 images, the 400 most significant interest points were detected. For interest points detected based on scale-space extrema, the image features were ranked on the scale-normalized response of the differential operator at the scale-space extremum. simple listview in android

Scale-space Extrema Detection. From the image above, it is obvious that we can't use the same window to detect keypoints with different scale. It is OK with small corner. But to detect larger corners we need larger windows. For this, scale-space filtering is used. In it, Laplacian of Gaussian is found for the image with various \sigma values. simple list of low carb foods
