Wavelets and warping PS seismic images [PDF]

SEG Technical Program Expanded Abstracts 2014, 2014
The process of warping a PS seismic image to align reflectors with those in a PP seismic image can cause wavelet distortion. This distortion can be reduced by deconvolving the PS wavelet from the PS image, warping to PP time, and then convolving with the PP wavelet.

Rapid Deep Vat Printing Using Photoclickable Collagen‐Based Bioresins

Advanced Healthcare Materials, EarlyView.
Collagen‐based resin formulations based on thiol‐ene photoclick chemistry are demonstrated. These resins enable easy handleability under neutral conditions and further allow facile fabrication of multicellular tissue constructs via tomographic or FLight printing.

Rectangling irregular videos by optimal spatio-temporal warping

Computational Visual Media, 2021
Image and video processing based on geometric principles typically changes the rectangular shape of video frames to an irregular shape. This paper presents a warping based approach for rectangling such irregular frame boundaries in space and time, i.e ...

Textile Encoding Inspired by Langer Lines via Elastically Graded Embroidered Tessellations

Advanced Materials, EarlyView.
A standard embroidery machine can encode skin‐like directional mechanics into stretchable fabrics that, when worn, augment the wearer's skin. Zigzag stitch patterns, inspired by skin collagen structure, pack extra slack in threads that, when tessellated, mimic Langer lines.

Discriminative image warping with attribute flow [PDF]

CVPR 2011, 2011
We address the problem of finding deformation between two images for the purpose of recognizing objects. The challenge is that discriminative features are often transformation-variant (e.g. histogram of oriented gradients, texture), while transformation-invariant features (e.g. intensity, color) are often not discriminative. We introduce the concept of

Volumetric 3D Printing and Melt‐Electrowriting to Fabricate Implantable Reinforced Cardiac Tissue Patches

Advanced Materials, EarlyView.
This study presents an implantable reinforced cardiac patch (RCPatch) combining volumetrically 3D‐printed metamaterials with melt‐electrowritten (MEW) meshes. The design integrates tunable stiff polymer structures with soft, cell‐laden hydrogels. The RCPatch withstands suturing, intraventricular pressure, and cardiac contraction in a large animal ...

Automatic face image annotation based on a single template with constrained warping deformation

IET Computer Vision, 2013
In this study, an automatic face image annotation method is proposed by aligning faces with different expressions to an annotated neutral face. This work is useful in reducing tedious manual work for labelling image data in large databases.
