For this purpose, the performance of Dense Scale Invariant Features (DSIFT) is evaluated by concentrating on Support Vector Machine (SVM) classifier. First of all, the concept ofk-means clustering is operated on DSIFT features and then images are represented with histograms of features by ...
we apply Fisher???s vector to reduce the dimension of feature description followed by the SVM linear classifier to improve the final classification result. The average accuracy of echocardiography video classification is 77.12% for all eight viewpoints and 100% for three primary viewpoints. 展开 ...

Wheat grain classification by using dense SIFT features with SVM classifier We put an automated system to classify the wheat grains with a high accuracy rate.We used the performance of DSIFT evaluated by SVM classifier.The proposed... MO Olgun,AO Onarcan,Kemal ,... - 《Computers & Electroni...
Machine learning classifiers such as random forest and linear support vector machine (SVM), were used in this study for instrument segmentation. Voros et al. (Voros et al., 2006) proposed a method based on the mathematical morphology of the 3D position of the insertion point of the surgical ...
Today, SIFT [14]/SURF [1] or dense sampling are widely used for still image classification as an interest point detection and a feature descriptor. And spatiotemporal interest points(STIP) [2, 6] or dense trajectory (DT) [21] are used for video classification in most cases. However, few...
SIFT or SURF. There is also at least one example of it being used for stereo matching [36]. However, to our knowledge BRIEF has not been used in the context of optical flow esti- mation, and not in combination with the PatchMatch algorithm. We will show that using the BRIEF descriptor...
(Dense_SIFT)as the local features of four typical cloud images.The extracted cloud features are then clustered by K-means algorithm,and the bag-of-words(BoW)model is used to describe each ground-based cloud image.Finally,support vector machine(SVM)is used for classification and recognition....
Using the UAV mapping and measurement software Pix4D (Lausanne, Switzerland) and SIFT algorithm, the adjacent images in the test set of the dataset were stitched together to synthesize a large scene of high-resolution banana forest orthorectified remote sensing image with a resolution of 4104 × ...
