To sample the four designated regions we used a template of appropriate size and shape to fit over a core portion of each designated area.
Using your beverage canister as a guide, mark a template of appropriate size at the top of the pumpkin around the stem.
This is achieved without any filtering, using a search template of size 21 × 21, and a number of clusters equal to 1/200 of the total number of training patterns.
As it is clear in Table 3, the least accurate result of K-means cases is obtained using KNN as filtering method, a search template of size 17 × 17, and a number of clusters equal to 1/800 of the total number of training patterns (i.e., a total number of 7,176 scanned patterns).
Finally, the most accurate E_type of Spectral cases is shown in Fig. 6e; using PCA as filtering method, a search template of size 17 × 17, and a number of clusters equal to 1/200 of the total number of training patterns has led to the most accurate result obtained through application of Spectral clustering.
The least accurate E_type of FILTERSIM using Spectral clustering method is demonstrated in Fig. 6d where it comes from KNN as filtering method, a search template of size 29 × 29, and a number of clusters equal to 1/200 of the total number of training patterns.
Here we performed 11C-PK11195 minroPET in a rat model previously shown to induce extensive cortical MA, and determined the correlation between 11C-PK11195 and immunostaining with the CD11 antibody OX42, so as to verify the presence of activated microglia, in a template of PET-resolution size regions-of-interest (ROIs) spanning the whole affected hemisphere.
Let be the image under examination, of size by pixels, the template, of size by pixels, and be the subimage of at position having the same size as the template, and let 〈 〉 and 〈 〉 be the computed mean of and of respectively.
For calculation of traction forces, square image blocks with a template size of 15 25 pixels = 2.5 4.1 µm (where the smaller template sizes were applied on the stiff 35 kPa substrates) were centered on each reference bead position, identified as intensity maxima in the reference frame.
