Panel Overview

🧭 Panel Overview

SubSpectra is split into 5 main panels, each focused on a different steganography task.

---

🖼️ Panel 1: Create Image

🔹 Purpose: Hide or extract messages in PNG/JPG images using LSB techniques.

🧰 Features:

• Hide short text into R/G/B/A channels
• Select which bit layer to embed into (0–7)
• Visual preview of individual bit planes
• Export stego image to disk
• Extract message from image

---

🎬 Panel 2: Create Video

🔹 Purpose: Hide a string in a video (frame-by-frame) and rebuild it using FFmpeg.

🧰 Features:

• Extract all frames from a video
• Hide 20-character string into center pixels (RGB)
• Save stego video using FFmpeg (with audio preserved)
• Extract hidden message
• Supports: MP4, MKV, AVI

---

🔎 Panel 3: Test Image

🔹 Purpose: Detect signs of manipulation in images via statistical analysis.

🧰 Features:

• View LSB layers (0–7) in R/G/B/A
• Toggle channels (R → G → B → A)
• Run Chi-square and RS tests
• Save results as Excel report
• Color-coded: ✅ OK, ⚠️ Suspect, ❌ Unnatural

---

🎥 Panel 4: Test Video

🔹 Purpose: Detect LSB steganography in videos using multiple frames.

🧰 Features:

• Extract first 50 frames
• Run Chi-square and RS test on bits 0 and 1 of R/G/B channels
• Generate an Excel file with scores and verdicts per frame
• Performance optimized to avoid lag

---

🎨 Panel 5: Filters

🔹 Purpose: Visually analyze and transform images using forensic filters.

🧰 Features:

• Remove individual bit layers from R/G/B/A
• Apply red, green, blue, grayscale, BW, sepia filters
• Block-based average filters (3×3 and 9×9)
• Highlight pixels that deviate from their 3×3 average (special filter)
• Save all results in a _filters folder beside the image

---

Each panel is optimized for a specific aspect of LSB steganography — from embedding to detection and filtering.
