A digital image is a representation of a physical or natural scene in the form of a two-dimensional array of discrete values called pixels. The process of digitizing an image involves three main steps: sampling, quantization, and coding.

What is the digital image about?

Sampling refers to the process of dividing the continuous image into a discrete grid of pixels. Quantization involves assigning a numerical value to each pixel, based on its intensity or color, and rounding it to the nearest integer value. Finally, coding involves representing these numerical values as binary codes to store or transmit the image.

The elementary point of a Bitmap image is called a "pixel" (short for "picture element").

White and black colors are obtained by additive synthesis by combining light of different wavelengths. White light is created by adding together all the colors of the visible spectrum, while black is the absence of light.

The size of the images can be calculated by multiplying the width by the height. Therefore:

An image with 2560 pixels in width and 1920 in height has a size of 4,915,200 pixels.An image with 200 pixels in width and 150 in height has a size of 30,000 pixels.An image with 405 pixels in width and 1230 in height has a size of 498,150 pixels.

Tu es un(e) explorateur(trice) chargé(e) d'une expédition scientifique au Venezuela.
Raconte ton périple sous la forme d'une lettre adressée à un(e) ami(e).

Cher(e) ami(e),

Je t'écris depuis le cœur de la jungle vénézuélienne, où je suis actuellement en mission scientifique avec mon équipe. Notre expédition a débuté il y a quelques jours, et je dois dire que chaque jour est plus excitant que le précédent.

Dès notre arrivée, nous avons été accueillis par la beauté incroyable de la forêt tropicale, avec ses arbres immenses et ses ruisseaux cristallins. Nous avons installé notre campement pas très loin d'une chute d'eau, ce qui est non seulement un spectacle magique, mais aussi parfait pour nous approvisionner en eau potable.

Nous avons déjà commencé à étudier la faune et la flore de la région. La biodiversité ici est incroyablement riche : nous avons déjà vu des singes hurleurs, des toucans, des papillons aux ailes si colorées que j'ai du mal à croire qu'ils sont réels, et bien d'autres choses encore. Bien sûr, il y a aussi des insectes, mais nous avons tout le matériel nécessaire pour nous en protéger.

Nous avons également commencé à travailler avec certaines communautés locales. Les habitants ici ont une connaissance incroyable de la forêt et nous en apprennent constamment plus sur ses secrets cachés. Nous essayons de les impliquer autant que possible dans notre travail scientifique, pour les remercier de leur hospitalité et partager nos connaissances.

Bien sûr, il y a des défis à relever aussi. Le climat ici est chaud et humide, et les sentiers peuvent être difficiles à parcourir. Mais dans l'ensemble, je suis tellement heureux de participer à une telle aventure. Nous avons encore beaucoup de travail à faire, mais je suis sûr que cela en vaut la peine.

Je dois te laisser maintenant - nous avons une expédition de nuit prévue. Mais je te tiendrai au courant de nos progrès. À bientôt mon ami(e) !

Bien amicalement,

[TON NOM]
