MIFT: A Moment-Based Local Feature Extraction Algorithm
We propose a local feature descriptor based on moment. Although conventional scale invariant feature transform (SIFT)-based algorithms generally use difference of Gaussian (DoG) for feature extraction, they remain sensitive to more complicated ...

Image feature extraction applied in classification techniques [PDF]
V rámci této bakalářské práci prozkoumáme metodu extrakce obrazových rysů zvanou Scale-Invariant Feature Transform. Extrahované rysy využijeme k trénování a testování klasifikační techniky zvané Support Vector Machine.

Keyframe detection in visual lifelogs [PDF]
The SenseCam is a wearable camera that passively captures images. Therefore, it requires no conscious effort by a user in taking a photo. A Visual Diary from such a source could prove to be a valuable tool in assisting the elderly, individuals with ...

In vivo IL‐10 produced by tissue‐resident tolDC is involved in maintaining/inducing tolerance. Depending on the agent used for ex vivo tolDC generation, cells acquire common features but prime T cells towards anergy, FOXP3+ Tregs, or Tr1 cells according to the levels of IL‐10 produced. Ex vivo‐induced tolDC were administered to patients to re‐establish/

Social context prevents heat hormetic effects against mutagens during fish development
This study shows that sublethal heat stress protects fish embryos against ultraviolet radiation, a concept known as ‘hormesis’. However, chemical stress transmission between fish embryos negates this protective effect. By providing evidence for the mechanistic molecular basis of heat stress hormesis and interindividual stress communication, this study ...

An improved localization method for lesion area in gynecological ultrasound image
The false positive and false negative rates of current image localization methods in gynecological lesion area are high because the effectiveness is affected by random noise.

Circulating tumor DNA (ctDNA) offers a possibility for different applications in early and late stage breast cancer management. In early breast cancer tumor informed approaches are increasingly used for detecting molecular residual disease (MRD) and early recurrence. In advanced stage, ctDNA provides a possibility for monitoring disease progression and

HSI-MSER: Hyperspectral Image Registration Algorithm Based on MSER and SIFT
Image alignment is an essential task in many applications of hyperspectral remote sensing images. Before any processing, the images must be registered.

Switched-capacitor networks for scale-space generation [PDF]
In scale-space filtering signals are represented at several scales, each conveying different details of the original signal. Every new scale is the result of a smoothing operator on a former scale.

Peripheral blood proteome biomarkers distinguish immunosuppressive features of cancer progression
Immune status significantly influences cancer progression. This study used plasma proteomics to analyze benign 67NR and malignant 4T1 breast tumor models at early and late tumor stages. Immune‐related proteins–osteopontin (Spp1), lactotransferrin (Ltf), calreticulin (Calr) and peroxiredoxin 2 (Prdx2)–were associated with systemic myeloid‐derived ...
