今天看DX9SDK for ManagedDX,不太顺心,后面的Direct3D Surfacces和Direct3D Textures两章,难呀。看SDK的英文
确实很吃力。感觉什么都没有学到,像是在浪费光阴...今天听了学校微软技术俱乐部两个MVP(微软最具价值专家),
有关的讲做,感觉他们凶啊....呜...,才20岁出头,同龄的我却毫无价值,思考他们的成长经历和我有什么不同...

今天也看了看《Managed DirectX 9 Kick Start: Graphics and Game Programming》,感觉有些东西还是要看SDK,
感觉这本书,前面很多地方都说得不是太透,光是让读者不要担心,后面将会涉及。作为一个看了大半部分SDK中的
Direct3d Graphics的我,我觉得:对于我看了的SDK,且看懂了的部分,我觉得SDK更好,更详细。(也许是我还没有
读到Managed DirectX? 9 Kick Start: Graphics and Game Programming 的后面部分吧),不管怎样,我下一步打算
看《Managed DirectX? 9 Kick Start: Graphics and Game Programming 》这个了,必竟看了SDK,也有一定基础了,
即使书中提及“现在不要担心,后面将会涉及”之类的,因为我心中了有底啦....作为一本入门的MangedDX的书,我相信
它能弥补我在SDK中看不懂的部分...

辐射制冷无规散射结构非球形散射体的结构优化与设计准则 本文针对辐射制冷材料中非球形散射体的光散射特性开展研究,提出了一种基于体积散射截面和不对称因子的综合评价方法。通过建立简化模型分析球体、圆柱体、长方体等六种几何形状在太阳波段的散射性能,发现金字塔形和圆锥形具有更强的后向散射能力。研究创新性地提出"反射因子SR=S(1-g)"这一评价参数,该参数与宏观反射率高度相关,为非球形散射体的优化设计提供了定量依据。仿真结果表明,合理选择散射体形状可显著提升辐射制冷材料的太阳反射率,为实现高效被动制冷提供了新的结构设计思路。 阅读详情

图像处理 | 基于matlab的多尺度Retinex(MSR)和自适应直方图均衡化(CLAHE)算法联合的低照度图像增强(附代码)

本文介绍了一种基于多尺度Retinex(MSR)和CLAHE的低照度图像增强算法。算法首先对图像进行多尺度Retinex处理,通过不同尺度的高斯核去除光照影响;然后采用CLAHE算法进行对比度增强。Matlab实现展示了算法流程,包含灰度转换、多尺度Retinex增强和CLAHE处理。实验结果显示,该方法能有效提升低照度图像的可见性,增强细节表现。最后提出了改进建议,包括引入深度学习方法和优化参数选择。

【Matlab算法】MATLAB实现的语音信号降噪算法(附MATLAB完整代码)

语音信号降噪是语音处理领域中的一个关键问题。在实际应用中,语音信号常常被各种环境噪声污染,这不仅影响了语音的质量,还可能导致后续处理(如语音识别)的性能下降。因此,开发有效的降噪算法对于提高语音通信质量、改善语音识别系统性能等具有重要意义。 本文将介绍并实现两种经典的语音信号降噪算法:谱减法和维纳滤波。这两种方法都是基于频域处理的技术,具有实现简单、计算效率高的特点。通过MATLAB实现这些算法,我们可以直观地比较它们的性能和降噪效果。
