Project 2 Stereo matching and homographies

Now use your putative match generation and RANSAC code from Part 1 to estimate fundamental matrices without ground-truth matches. For this part, only use the normalized algorithm. Report the number of inliers and the average residual for the inliers. In your report, compare the quality of the result with the one you get from ground-truth matches.

“We don’t have much ground truth in biology.” According to Barbara Engelhardt, a computer scientist at Princeton University, that’s just one of the many challenges that researchers face when trying to prime traditional machine-learning methods to analyze genomic data.

The sparse SIFT matches provides us with the op-tical flow at these feature points. The (x,y) location of the matches between the two images can be used to compute the flow vectors at these points. This set of sparse flow vectors at the interest points is the seed for the prediction step. Using the flow at these seed locations, we use an itera-tive algorithm, SWIFT-flow (Algorithm3), to

Clearly, SIFT flow matches better to human annotation than minimum L1-norm SIFT matching. 5 Dense Scene Alignment Applications As illustrated in the previous section, we are able to find dense scene correspondences between two images using SIFT flow, and the correspondence can be semantically meaningful if the two images contain similar objects.

Experimental results and comparisons conducted on the Ground truth image benchmark prove the robustness of proposed framework based on the visual words integration of SIFT and SURF. The mean average precision obtained from the proposed visual words integration is higher than that of the existing state-of-the-art research [ 36 , 59 , 60 ].

Table 2 from A Ground Truth For Half A Million Musical

This large collection size makes a ground truth very interesting for the development of music retrieval methods, but at the same time makes it very difficult to establish one. Human experts cannot be expected to sift through half a million melodies to find the best matches for a given query. For 11 queries, we filtered the collection so that about 50…
