Image stitching or photo stitching is the process of combining multiple photographic images with overlapping fields of view to produce a segmented panorama or high-resolution image. Commonly performed through the use of computer software, most approaches to image stitching require nearly exact overlaps between images and identical exposures to produce seamless results, although some stitching algorithms actually benefit from differently exposed images by doing high-dynamic-range imaging in regions of overlap. Some digital cameras can stitch their photos internally.

  • L'assemblage de photos est un procédé consistant à combiner plusieurs images numériques se recouvrant, dans le but de produire un panorama ou une image de haute définition. (fr)
  • Lo stitching di immagini è un metodo col quale si combinano molteplici immagini fotografiche per produrre un panorama o un'immagine ad alta risoluzione. Comunemente si fa ricorso a dei software, tenendo conto che per un'immagine senza soluzione di continuità è necessario che le varie parti siano tagliate in riferimento a dei margini comuni e abbiano la stessa esposizione. Alcune fotocamere digitali possono compiere processi di stitching in automatico. L'isola di Alcatraz vista in un esempio di panorama realizzato mediante stitching. (it)
  • 影像拼接(image stitching)是指將兩張或更多的有重疊部分的影像,拼接成一張全景圖或是高解析度影像的技術。影像拼接有兩大步驟:影像對準(image alignment)和影像混合(blending),相關的應用有: * 影像穩定(image stabilization) * 影片摘要(video summarization) * 背景擷取 * 全景圖製作 但並不是任意兩張有重疊部分的影像都能夠被拼接,被拼接的影像必須: * 有同樣的投影中心 * 影像的內容為平面,沒有前後景的分別 * 影像為足夠遠的遠景,可以視為平面 實作上,通常會固定相機,讓影像能有相同的投影中心以利後續處理。另外影像之間重疊部分不宜太少或太多,重疊太少會讓對準變得困難,重疊太多則會讓混合之後的瑕疵和失真更多,適當的重疊範圍為15-30度。另外,為了讓拼接後的影像更符合人類視覺,在進行影像拼接之前,會先將影像投影到圓柱座標或球體座標上, (zh)
  • La unió d'imatges o unió de fotos és el procés de combinar múltiples imatges fotogràfiques (amb camps de visió que es superposen en els extrems) per produir una imatge d'alta resolució o panorama segmentat. Comunament es realitza mitjançant l'ús de programes informàtics perquè no es vegin les "costures" d'unió aconseguint superposicions gairebé exactes entre les imatges i exposicions idèntiques. Algunes càmeres digitals poden unir les seves fotos internament. La unió d'imatges s'utilitza àmpliament en el món d'avui en aplicacions com ara: (ca)
  • Stitching (englisch stitch „nähen“, „heften“) bezeichnet in der Fotografie das Erstellen einer großen Fotografie aus verschiedenen kleineren Einzelaufnahmen, die (in der Regel überlappende) Ausschnitte des Motivs zeigen. Stitching wird genutzt, wenn eine Einzelaufnahme nicht den gewünschten Bildwinkel erfassen würde, also als Ersatz für ein Weitwinkelobjektiv oder gar zur Herstellung eines 360°-Panoramas, oder um für großformatige Bilder eine größere Auflösung (Pixelzahl) zu erzielen, als es mit einer Einzelaufnahme aufgrund der beschränkten Auflösung der Kamera möglich wäre.
