Crop, reduce, and dither images to 8-bit retro formats.

This is a quick and dirty, image viewer made in Assembly that is designed specially for interlaced and linear RAW CGA image data in mind. I've created this tool way back in May of 2022 to improve my machine language skills, while experimenting with various image file formats.

The Color Graphics Adapter (CGA), originally also called the Color/Graphics Adapter or IBM Color/Graphics Monitor Adapter, [1] introduced in 1981, was IBM's first color graphics card for the IBM PC and established a de facto computer display standard.

This program takes in an image, quantizes it, and interlaces/modifies the data to be loaded directly into CGA ram. Optionally adding a small "loader" to the start and exporting as a COM file. This COM file can then be run on a CGA compatible computer and will display the image, waiting for a key-press before closing.

CGA-based Mixup Fusion Scheme. 作者提出了一种基于CGA的混合方案，通过学习的空间权重来调制特征，自适应地将编码器部分的低级特征与相应的高级特征融合在一起。 下图显示了所提出的基于 CGA 的混合融合方案的细节。

2024年3月9日 · CGA（Content-Guided Attention）是一种内容引导注意力机制，用于提高图像恢复任务中神经网络的性能。CGA是一种粗细处理过程，首先生成粗略的空间注意力图，然后根据输入特征图的每个通道进行细化，以产生最终的空间注意力图。

A little utility that takes an image and produces a reduced version of it compatible with old CGA, EGA, and VGA graphics modes.

2024年12月22日 · 内容引导注意力（CGA）：为每个通道分配独特的空间重要性图（SIM），能够关注特征中编码的更多有用信息。 基于CGA的混合融合方案：有效地融合特征并辅助梯度流动，提升去雾效果。 DEConv的实现：使用五个卷积层（四个差分卷积和一个普通卷积）并行部署，通过计算像素对差异并将先验信息显式编码到CNN中。 CGA的设计：采用两步注意力生成器，首先生成粗略的空间注意力图，然后细化为精细版本，为每个通道分配唯一的SIM。 整体架构：采用 …

2021年9月15日 · I'm back with a new python script for vintage PC compatibles! This script takes in a JPG image, and outputs a COM file suitable for execution on any IBM PC / CGA compatible computer! It supports any modes ranging from 640x200 2 color up …

Many full screen CGA images store their data in interlaced format, so that they can be loaded directly into video memory without any additional processing. In some of these cases however, the data is loaded in one operation for the entire image …
